A household earns $2,800 a month. Rent takes 30 percent, food costs $420, and other expenses come to $310. How much is left?

Correct answer to question 95 (Arithmetic Reasoning): $1,230

Method

Rent is 0.30 x 2,800 = $840. Subtracting all three expenses, 840 + 420 + 310 = $1,570, leaves 2,800 - 1,570 = $1,230.
