Answer:

Roger works 30 hours and his brother works 50 hours

Step-by-step explanation:

Let

x ---->the number of hours Roger works in a month

y ---->the number of hours his brother works in a month

step 1

Find out how much they earn per hour

5,400-3,240=$2,160 -----> amount earned by 20 hours of work

$2,160/20=$108 per hour

step 2

Find out how many hours each brother works in a month

108*x=3,240

x=3,240/108=30 hours

His brother

y=x+20

y=30+20=50 hours
