Reilly, Maria, and Tamara figured out that the ratio of the times they spent painting a deck is 3:5:1. They are going to use this ratio to share the $36.90 they earned. How much will Maria get?

3+5+1= 9
divide 36.90 by 9 and you get 4.1 for every 1 part they get. Reilly gets 3 parts so multiply 4.1 by 3 and you get $12.30 as reilly’s total. maria gets 5 parts so multiply 4.1 by 5 and you’ll get $20.50 as maria’s total and then tamara will get $4.10. answer is $20.50 since that’s how much maria got!
