(5.3K) Warren's family travelled to different locations every year for 4 years. The table shows how many miles they traveled each year.

They travelled 22,115 less miles in year 4 than they did in year 2. What is the total number of miles Warren's family travelled in all 4 years?

• 177,986 miles

• 692,816 miles

• 536,945 miles

• 492,715 miles

Answer explanation

In the question, it's stated that Warren's family traveled 22,115 less miles in year 4 than in year 2. Year 2's distance is 200,101 miles, so year 4's distance is 200,101 - 22,115 = 177,986 miles. Adding the distances for all four years (155,725 + 200,101 + 159,004 + 177,986), the total distance travelled is 692,816 miles. Hence, the correct answer is 692,816 miles.

• 77

• 92

• 29

• 49

Answer explanation

By following the order of operations, first perform the division inside the parentheses, 4 divided by 2, which equals 2. Then, multiply 4x2, which equals 8. After, perform the multiplication 3x7, which equals 21. Finally, add 8 and 21, which equals 29. So, the correct answer is 29.

(5.4B) Pedro had 185 pieces of wood. He sold 25 pieces of wood to his neighbor and stacked the rest of the wood into piles around his house. Each pile of wood contained 40 pieces of wood. Which equation can be used to find p, the number of piles of wood Pedro made?

Answer explanation

Pedro had 185 pieces of wood and he sold 25, leaving him 185 - 25 = 160 pieces. He then stacks these pieces into piles, with each pile containing 40 pieces. So, the number of piles, p, is found by dividing the number of pieces left by the number of pieces in each pile, which is (185-25) ÷ 40. This is why the correct equation is p = (185-25) ÷ 40.

(5.4B) A family spent $93 at a carnival.

• They spent $18 on tickets to the carnival and $36 on food.

• They spent the rest of the money on games.

Which equation can be used to find g, the amount of money in dollars the family spent on games?

Answer explanation

The family spent a total of $93 at the carnival, which includes $18 on tickets, $36 on food, and the rest on games. To find the amount spent on games, we need to subtract the cost of the tickets and food from the total amount. Therefore, the correct equation is $93 = g + $36 + $18, where g represents the amount spent on games.

(5.4B) Foot Locker has the biggest supply of sports shoes in town. They sold 3,442 shoes last month, and have sold 4,107 shoes this month. They still have 9,819 shoes in stock left to sell.

How many shoes did Foot Locker have before they started selling shoes last month?

• 2,270 shoes

• 17,368 shoes

• 16,549 shoes

• 6,377 shoes

Answer explanation

The total number of shoes Foot Locker had before they started selling can be obtained by adding the shoes sold last month, this month and the remaining stock. That is 3,442 (last month) + 4,107 (this month) + 9,819 (remaining) = 17,368 shoes. So, the correct answer is 17,368 shoes.
