Solutions

Question 1
Let x be the number of green marbles Samantha has. Total marbles = 20 Blue marbles = 6 Yellow marbles = 10 Green marbles = x 20 = 6 + 10 + x Simplifying above equation, we get x = 20 - 6 - 10 = 4 Therefore, Samantha has 4 green marbles in her bag.

Question 2
Multiply the amount of honey scooped per scoop by the number of scoops taken and subtract that amount from the total amount of honey in the jar: (15 g/scoop) x 4 scoops = 60 g scooped out. 300 g - 60 g = 240 g of honey is left in the jar.

Question 3
To find out how much Janet spent on buying other stuff, we need to subtract the amount she spent on food and entertainment from the total amount she spent. Therefore, we can use the following equation: $220 - $70 - $90 = $60. So, Janet spent $60 on buying other stuff.

Question 4
There are 291 pets in total.

Question 5
To find the total number of action figures, we need to add the number of good ones to the number of broken ones. Let x be the total number of action figures. Then the equation representing the problem is: x - 2 = 7. Solving for x, we get x = 9. Therefore, there were 9 action figures in total.

Question 6
To find the total number, we can simply add the number of males and females. Total = 201 + 321 Total = 522 Therefore, Mr. Johnson was able to feed 522 people in total.

Question 7
Add 24 and 52 to find the total number of apples Sandy and Billy have. 24 + 52 = 76. They have 76 apples altogether.

Question 8
To find out how much Karen spent on other miscellaneous items, we can subtract the amount she spent on paint, brushes, and canvas from the total amount she spent. This gives us: $50 - $16 - $9 - $25 = $50 - $50 = $0. Therefore, Karen did not spend any money on other miscellaneous items.

Question 9
To find the total number of sweets, we need to add the number of chewing gums, chocolate bars, and assorted fruit candies Thomas got. Therefore, Thomas got a total of 8+12+18 = 38 sweets.

Question 10
To find out how many cookies Jose baked, we need to add the number of peanut butter cookies he baked yesterday (435) to the number of cookies he baked this morning (139). Adding these numbers together, we get: 435 + 139 = 574 Therefore, Jose baked 574 cookies in total.

Question 11
To find the total number of factories inspected by both groups, we need to add the number of factories visited by Sarah's group, the number of factories visited by the other group, and the number of factories they visited together. 83 + 41 + 35 = 159 Therefore, the two groups inspected a total of 159 factories.

Question 12
The East and West team cooked 240 plates of taco. The South team cooked 75 plates less, so they cooked 240-75=165 plates of tacos. To find the total number of tacos, we add the plates cooked by all the teams: 240+165=405. Therefore, the teams altogether cooked 405 plates of tacos.

Question 13
To find the total number of slices of pizza, we need to add the number of slices Timothy purchased, the number of slices his sister purchased, and the number of slices provided by their coworker. Total slices of pizza = 48 + 48 + 27 = 123.

Question 14
Step 1: Calculate the total weight of the small bags. 6 ounces/bag x 6 bags = 36 ounces. Step 2: Calculate the total weight of the large bags. 10 ounces/bag x 3 bags = 30 ounces. Step 3: Add the total weight of the small bags to the total weight of the large bags. 36 ounces + 30 ounces = 66 ounces. Therefore, the total weight of 6 small bags and 3 large bags of gummy bears is 66 ounces.

Question 15
Subtract the number of amethysts from the number of pearls. 722 - 356 = 366. There are 366 more pearls than amethysts.

Question 16
To find the total number of pots, bags, and tools in the garden center, we simply add the number of pots, bags, and tools. Total number of pots, bags, and tools = 25 pots + 12 bags + 8 tools Total number of pots, bags, and tools = 45.

Question 17
Subtract the number of fish species that went away from the original number of fish species to get the number of fish species left in the lake. 39 - 19 = 20. Therefore, there were 20 fish species left in the lake.

Question 18
To find out the number of animals in the zoo, we need to add the number of tigers and lions. Therefore, we can add: 157 + 18 = 175 So, there are 175 animals in the zoo.

Question 19
Add the number of monkeys and the number of pigs to get the total number of animals in the farm. Total number of animals = 528 + 410 = 938.

Question 20
Step 1: Determine the number of orange and brown flowers needed to have the same number of each. As stated in the problem, the number of orange flowers is the same as the number of brown flowers. Therefore, we know that there are 694 orange flowers and 939 brown flowers. Step 2: Subtract the number of orange flowers from the number of brown flowers to find the difference. Using the given numbers, 939 - 694 = 245. Step 3: The answer is the difference found in step 2. Therefore, 245 more orange flowers are needed.
