Ty paid an average cost of $14.24 per book

Cam paid an average cost of $15.47 per book

So, Cam paid an average cost of $1.23 more per book than his brother

Step-by-step explanation:

Two brothers, Ty and Cam, went to a local bookstore to buy books for school

  • Ty bought 8 books for $113.92
  • Cam bought 6 books for $92.82

They want to compare their average cost per book

The average cost of any items = total cost of them ÷ their numbers

∵ Ty bought 8 books for $113.92

- Use the rule above

∵ The total cost of books = $113.92

∵ The number of books = 8

∴ The average cost per book = 113.92 ÷ 8 = 14.24

∴ The average cost is $14.24 per book

Ty paid an average cost of $14.24 per book

∵ Cam bought 6 books for $92.82

- Use the rule above

∵ The total cost of books = $92.82

∵ The number of books = 6

∴ The average cost per book = 92.82 ÷ 6 = 15.47

∴ The average cost is $15.47 per book

Cam paid an average cost of $15.47 per book

∵ 15.47 > 14.24

∴ Cam average cost is more than Ty average cost

∵ 15.47 - 14.24 = 1.23

∴ Cam average cost is more than Ty average cost by $1.23 per book

So, Cam paid an average cost of $1.23 more per book than his brother
