Question

Three roommates share their monthly rent payment in a ratio of 7 : 8 : 10. If the monthly rent is $1,200, then what is the amount of the greatest share?

Answer 1

$480

Explanation:

1) 7x + 8x + 10x =1200

25x=1200

x=48, where x is the amount needed to multiply

2) The greatest amount of share is the roommate paying 10 (in the ratio)

Using the x from Step 1 multiply 10 with 48

48 x 10

=480

Answer: $480
