Melissa, Charlie, and Josh have a total of $90 in their wallets. Josh has 3 times what Charlie has. Melissa has $10 less than Charlie. How much does each have?

$20 = Charlie, $60 = Josh, $10 = Melissa

Step-by-step explanation:

M+C+J=90  = Melissa, Charlie, and Josh have a total of $90 in their wallets

J=3C = Josh has 3 times what Charlie has

M=C-10 = Melissa has $10 less than Charlie.

Therefore

M+C+J=90

(C-10) + C + 3C=90

5C-10=90

5C=100

C=20 = Charlie

J=3C = 60 = Josh

M=C-10 = 10 = Melissa

answer: 20
