Let the variable s represent the amount Trey saved before mowing lawns. Trey earns s dollars. Then he earns an additional $40. So far, he earns (s+40). Then this amount is doubled: 2(s+40) At the end, he has $234. So the equation is 2(s+40) = 234 2s + 80 = 234 2s = 154 s = 77 An arithmetic approach (solving using addition) could have the equation as (s+40) + (s+40) = 234 s + 40 + s + 40 = 234 2s = 154 s = 77
