Question

My mother pays my brother twice as much allowance each week as she pays me because he cleans the bathrooms. Together we get $27 each week. How much is my brother's allowance each week? A. $4.50 B. $9 C. $18 D. $27

Answer 1

C. $18

Explanation:

The ratio between brother and her is 2:1. Therefore, there are 3 parts. $27/3 = $9. Thus, her brother gets 2*$9 = $18 and she gets 1*$9 = $9

Answer 2

B

Explanation:

Brother= 9*2=18

Me= 9

B+M= 18+9= 27
