Question

Mai, Bill, and Dante have a total of $105 in their wallets. Dante has 3 times what Mai has. Bill has $10 more than Mai. How much does each have?

Answer 1

Mai 19

Bill 29

Dante 57

Explanation:

assume

mai = X

Bill = Y

Dante = Z

X + Y + Z = 105

Z = 3X

Y = 10 + X

then

X + Y + Z = X + 3X + 10 + X

5X + 10 = 105

5X = 95

X = 19

Y = 29

Z = 57
