Question

Heather, David, and Kevin have a total of $90 in their wallets. David has $6 less than Heather. Kevin has 2 times what David has. How much do the have in their wallets

Answer 1

• Heather, $27
• David, $21
• Kevin, $42

Explanation:

Let d represent the amount David has. Then Heather has d+6 and Kevin has 2d. The sum of these amounts is ...

d +(d+6) +2d = 90

4d = 84

d = 21 . . . . . . David's amount

d+6 = 27 . . . Heather's amount

2d = 42 . . . Kevin's amount
