Amiddle-school band holds a car wash to raise money. the sixth-grade band members wash 16 cars. the seventh-grade band members wash 75% as many cars as the sixth-graders. the eighth-grade band members wash half as many cars as the sixth- and seventh-grade band members combined. if the band charges $5 per car, how much money did the members raise altogether?

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
