Question

Penny and Ben saved their money to buy a gift for their money. Together, They collected a total of $42. Ben saved twice as much money as Penn. How many dollars did Ben save?

Answer 1

Ben saved 28 dollars

Explanation:

Let b = the money Ben saved.

Let p = the money Penny saved.

b = 2p

p + b = 42 Substitute 2p for b and solve for p

p + 2p = 42 Combine like terms

3p = 42 Divide both sides by 3

p = 14

Penny saved 14 dollars.

b = 2p substitute 14 for p

b = 2(14)

b = 28

Ben saved 28 dollars.
