Answer 1

Answer: 1) Each friend had contributed $6.25.

2)The expression to show how many books Aaron read in p months :

`y=9p`

He reads 54 books in 6 months.

Explanation:

1) Given : The total number of friends who contributed equal amounts of money to buy a present. : 4

The total amount they have = $25

`=\frac{\text{Amount collected}}{\text{Number of friends}}\\\\=(25)/(4)=6.25`

Hence, each friend had contributed $6.25.

2) Given : The number of books Aron reads each month = 9 books

Let the number of months be 'p'.

Then the expression to show how many books Aaron read in p months .

`y=9p`

Then , the number of books Aaron read if he read for 6 months.

`y=9(6)=54`

Hence, he reads 54 books in 6 months.
