Question

Avi and Sergi are saving money to buy a game system. Avi has $2 more than double the amount of money Sergi has. Together, they have $40. Write an equation to determine how much money Sergi and Avi have together. x + 2x + 2 = 40 2x + 2 = 40 x + 2x − 2 = 40 2x − 2 = 40

Answer 1

x + 2x + 2 = 40

Explanation:

If we let x represent the money Sergi has, then Avi has twice that plus $2, or ...

2x +2

The total they have together is ...

Sergi + Avi = 40

x + (2x +2) = 40

x + 2x + 2 = 40 . . . . . written without parentheses, to match answer choices
