Question

September 6 is a Read Book Day.Polina read 5 times as many pages as Marcus read.Together,the read 108 pages.How many pages did each person read?

Answer 1

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

`5y+y=108\\6y=108\\y=18`

Find the value of x

`x=5y -----> x=5(18)=90`

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
