You are asked to find two unknown amounts. Victor’s earnings: x   Represent the amounts using algebra. Tami’s earnings: x 4,160   Write an equation showing that the sum of the   two amounts is $33,280. Solve the equation. x x 4,160 33,280   Combine like terms. 2x 4,160 33,280   Subtract 4,160 from both sides of the equation. 2x 4,160 4,160 33,280 4,160   2x 29,120   Divide both sides by 2.   x 14,560   Now go back to the beginning, when you first wrote the amounts in algebraic language. Since   x represents Victor’s earnings, you know that Victor earns $14,560 per year. Tami’s earnings are   represented by x+4,160. Add: 14,560+4,160=18,720. Tami earns $18,720 per year.   Answer: Victor earns $14,560, and Tami earns $18,720.   correct answer $18,720
