Solutions

Question 1
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 2
To solve for a, we can set up the equation: 8a = 136 Then we can divide both sides by 8, to get: a = 17. Therefore, there were 17 visitors at the zoo.

Question 3
Emma invited a total of 15 + 8 = 23 children from school and neighbourhood. Including Emma and her three siblings, there will be a total of 23 + 1 (Emma) + 3 (siblings) = 27 children at the party.

Question 4
To find the number of copies of the album that remain to be sold, we need to subtract the number of copies sold from the total number of copies released. Therefore, we can use the following equation: Total copies released - Copies sold = Copies remaining to be sold. Substituting the given values, we get: 754 - (354 + 243) = 157. Therefore, there are 157 copies of the album that remain to be sold.

Question 5
To solve for b, we can set up the equation: 5b = 125 Then we can divide both sides by 5, to get: b = 25 Therefore, there were 25 skaters at the skating rink.

Question 6
To find the total mass of the snacks David bought, we need to first calculate the mass of the trail mix and the pretzels. The mass of the trail mix is 10 bags x 8 oz/bag = 80 oz. The mass of the pretzels is 4 bags x 5 oz/bag = 20 oz. The total mass of the snacks is therefore 80 oz + 20 oz + 6 cans of iced tea. We need to convert the total mass from ounces to pounds and ounces. There are 16 ounces in a pound, so 80 oz + 20 oz = 100 oz, which is equal to 6 lbs 4 oz. Adding the mass of the 6 cans of iced tea, we get a total mass of 5 lbs 10 oz.

Question 7
To find out how much more fuel the new tank can hold, we need to subtract the old tank's capacity from the new one's. Therefore, the new tank can hold 80 - 60 = 20 liters more fuel.

Question 8
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 9
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 10
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 11
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 12
To find out the total deduction from Samantha's salary, we need to add up her rent, food, and tax bills. Rent + food + tax = $200 + $100 + $600 = $900. Therefore, $900 would be deducted from Samantha's salary, including the rent and food bills.

Question 13
To find the cost of one box of cheese, we need to divide the total cost of cheese by the number of boxes. Total cost = $4.20 Number of boxes = 3 $4.20/3 = $1.4 Therefore, each box of cheese costs $1.4.

Question 14
To find the amount saved, we need to first calculate how much it would cost to buy four boxes of pencils individually. To buy one box of pencils costs $3, so four boxes would cost $12. However, buying four boxes together costs $10.80. To find the amount saved, we subtract the cost of buying four boxes together from the cost of buying four boxes individually: $12 - $10.80 = $1.20. Therefore, you can save $1.20 by buying four boxes at the same time.

Question 15
To find out how many tickets are left to be sold, we need to subtract the number of tickets that have already been sold and the number of tickets that were purchased but never claimed from the total number of tickets required. So, Total number of tickets required = 1200 Number of tickets already sold = 868 Number of tickets purchased but never claimed = 92 Tickets left to be sold = Total number of tickets required - Number of tickets already sold - Number of tickets purchased but never claimed Tickets left to be sold = 1200 - 868 - 92 Tickets left to be sold = 240

Question 16
Linda spent $9 on 3 loaves of bread, so each loaf costs $9 / 3 = $3.

Question 17
To find the total number of informational materials given out, we need to add the number of maps and brochures. Thus, the solution is: 120 + 220 = 340.

Question 18
Let x be the number of encyclopedias purchased by the school. Then we have: 80 (textbooks) + 30 (workbooks) + x (encyclopedias) = 120 Simplifying, we get: x = 10 Therefore, the school bought 10 new sets of encyclopedias.

Question 20
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.
