Solutions

Question 1
7+4+1+1=13, not 14 children. The answer is incorrect.

Question 2
To find the total number of meals served, we need to add the number of lunches and breakfasts. Thus, the solution is: 200 + 150 = 350.

Question 3
To find the number of cupcakes left, we need to subtract the number of cupcakes that were eaten and sold from the original number of cupcakes. 523 - 92 - 36 = 395 Therefore, there are 395 cupcakes left.

Question 5
After filling up the 350 ml capacity bowl, there will be 600 ml - 350 ml = 250 ml of soup left in the pot.

Question 6
To find the difference between the soda in the bottle and can, we subtract the ml of the can from the ml of the bottle: 750 - 330 = 420. Therefore, there is 420 ml less soda in the can compared to the bottle.

Question 7
To find the total number of tickets sold in the three days, we need to add the number of tickets sold on each day. Total tickets sold = 47 + 84 + 63 Total tickets sold = 194 Therefore, 194 tickets were sold in three days.

Question 8
1 L = 1000 ml So, the jar originally had 3000 ml of milk. Ms. Davis used 1120 ml of milk. Therefore, the amount of milk left in the jar is 3000 ml - 1120 ml = 1880 ml. Converting ml to liters and millimeters, we get 1 L and 880 ml.

Question 9
5-2=3 gallons of paint leftover

Question 10
To find the total number of items sold, you can simply add the number of action figures and board games sold. So, 130 + 90 = 220. Therefore, the toy store sold a total of 220 items during the sale.

Question 11
To find the capacity of the new water tank, we add the extra capacity to the original capacity: 500 L + 300 L = 800 L. So, the capacity of the new water tank is 800 L.

Question 12
To find the total number of pieces of fruit in the store, we need to add the number of apples, oranges, and bananas. 875 + 215 + 136 = 1226. Therefore, the store has a total of 1226 pieces of fruit.

Question 13
To find the number of offensive players, we subtract the number of defensive players from the total number of players: 57 - 23 = 34. Therefore, the team has 34 offensive players.

Question 14
1. Multiply the number of boxes filled with fiction books by the number of books in each box. 4 boxes x 80 books/box = 320 fiction books.

Question 15
To find how much cement still needs to be delivered, we subtract the amount that has already been delivered (185 kg) from the total order (450 kg). Therefore, 450 kg - 185 kg = 265 kg. Therefore, 265 kilograms of cement still need to be delivered.

Question 16
Step 1: Calculate the total cost of 3 books, which is 3 x $5.50 = $16.50. Step 2: Compare the total cost with Susan's remaining money, which is $15. Step 3: Since $15 is less than $16.50, Susan will not have enough money to buy 3 books.

Question 17
Ms. Johnson used 2125 ml of the red paint, which leaves 5000 ml - 2125 ml = 2875 ml of red paint left in the container. Converting 2875 ml into liters and millimeters gives us 2 L 875 ml.

Question 18
The number of large pizzas that are not burnt is 16-3=13. The total number of large pizzas each customer will get is 13/4=3.25. Since we cannot give out a fraction of a pizza, each customer will get 3 large pizzas.

Question 19
To compare the amount of gas held by 3 cars and 100 bicycles, we need to calculate the total amount of gas each can hold. 3 cars can hold 3 x 15 = 45 gallons of gas. 100 bicycles can hold 100 x 1/2 = 50 gallons of gas. Therefore, 3 cars hold more gas than 100 bicycles, and the difference is 45 - 50 = 35 gallons.

Question 20
1. The novel costs $55, which is more than $50, so it qualifies for a $10 discount. 2. Each academic book costs $40, and Kelly is buying 3, so the total is 3 x $40 = $120. 3. Since Kelly is buying 4 books in total, she gets a discount of $15 on the fourth book. This means she gets a discount of $15 on the academic book that costs $40. 4. Therefore, the total cost for the academic books is $120 - $15 = $105. 5. The total cost for all the books is $55 + $105 = $160. 6. However, Kelly gets a discount of $10 for buying a book that costs $50 or more, so her final cost is $160 - $10 = $150. 7. Therefore, Kelly needs to pay $145.
