Solutions

Question 1
z = x + y

Question 2
1. Add the initial number of spoons and the additional spoons: 6 + 10 = 16 2. Add the initial number of forks and the additional forks: 4 + 18 = 22 3. Add the total number of spoons and forks: 16 + 22 = 38 Therefore, Jeff and his friends have 38 utensils available for the party.

Question 3
To find the total number of eggs Marie found, we add up the number of eggs from each location. So, 14 + 6 + 9 = 29. Marie also found 4 dimes, which do not relate to the number of eggs. Therefore, Marie found 29 eggs.

Question 4
Add 435 and 139 to get 574. Therefore, Tracy baked 574 cookies in total.

Question 5
To find the number of marbles John has now, we need to add the marbles he found outside to the marbles he has left after giving some away. Starting with 16 marbles, John gave away 3 marbles, which leaves him with 13 marbles. He then found 6 more marbles outside, which brings his total to 19 marbles.

Question 6
Step 1: Find the total number of balloons Marie had originally by adding the number of balloons she popped and the number she has left: 50 - 20 + n = 27. Step 2: Simplify the equation: 30 + n = 27. Step 3: Solve for n: n = -3. Therefore, Marie gave away 3 balloons to her little sister.

Question 7
The total number of balloons Olivia had can be represented as 60. After giving 25 balloons to her friend, she had 60 - 25 = 35 balloons left. After losing t balloons, she had 35 - t balloons. And finally, she had 20 balloons left. So, the equation can be written as 35 - t = 20. Solving it, we get t = 15. Therefore, Olivia lost 15 balloons that day.

Question 8
To find the number of classic movies Charlotte has left, we need to subtract the number of movies she donated (26) from the original number she had (81). Therefore, the solution is: 81 - 26 = 55. Charlotte has 55 classic movies left.

Question 9
To find the weight of the smaller box of candy, we need to subtract 6 ounces from the weight of the larger box. Therefore, the weight of the smaller box of candy is 18 ounces (24 ounces - 6 ounces).

Question 10
To calculate the amount of additional metal that Anna needs to buy, we need to subtract the weight she has in storage from the weight she needs. Therefore, the calculation will be: Additional metal = Total metal needed - Metal already in storage Additional metal = 124 - 81 = 43 pounds. Therefore, Anna needs to buy 43 pounds of additional metal.

Question 11
The first book weighs 2 pounds. The second book weighs 1 pound less than the first book, which means it weighs 1 pound. Hence, the second book weighs 1 pound.

Question 12
To find out how many foods Ben gave in all, we need to add the number of sandwiches (75) with the number of ice creams (487). This gives us the total number of foods he gave, which is 562. So, Ben gave a total of 562 foods in all.

Question 13
Subtract the number of stuffed animals sold from the total number of stuffed animals in the store: 50 - 29 = 21. There are 21 stuffed animals still in the store.

Question 14
Let's assume that Amelia has x dollars. Then, Amelia's friend has x - 5 dollars. We know that Amelia's friend has $11, so we can set up an equation: x - 5 = 11. Solving for x, we add 5 to both sides: x = 16. Therefore, Amelia has $16.

Question 15
Subtract the amount of gasoline in the tank from the maximum capacity of the tank: 20 L - 10 L = 10 L. Therefore, 10 L more gasoline is needed to fill up the tank.

Question 16
1. Multiply the number of shakes by the number of ounces of ice cream in each shake: 3 x 16 = 48 2. Add the number of ounces of ice cream in the shakes to the total number of ounces of ice cream served: 48 ounces Answer: Max served 48 ounces of ice cream.

Question 17
Emma had 300 - (12*25) = 0 buttons left.

Question 18
The cost for 1 person is $10, so for 3 people it is 3 x $10 = $30. To find the remaining budget, we need to subtract the total cost from the budget, which is $50 - $30 = $20. To find the number of people they can bring with that budget, we need to divide the remaining budget by the cost for 1 person. So, $20 / $10 = 2. They can bring 2 more people with them.

Question 19
To find out how much chips Jesse's uncle should prepare, we need to add the number of chips prepared by Jesse and his aunt, and then subtract that amount from the total amount of chips they want to have. This can be represented by the equation: 350 + 268 + x = 800 where x is the number of chips Jesse's uncle should prepare. Solving for x, we get: x = 800 - 350 - 268 x = 182 Therefore, Jesse's uncle should prepare 182 grams of chips.

Question 20
Step 1: Determine the number of yellow and green flowers needed to have the same number of each. As stated in the problem, the number of yellow flowers is the same as the number of green flowers. Therefore, we know that there are 522 yellow flowers and 786 green flowers. Step 2: Subtract the number of yellow flowers from the number of green flowers to find the difference. Using the given numbers, 786 - 522 = 264. Step 3: The answer is the difference found in step 2. Therefore, 264 more yellow flowers are needed.
