For spring cleanups, a landscaper charges a flat fee of $60 plus $20 for each hour of labor. Which equation models the cost in dollars, c, for a cleanup that requires h hours of labor? c = StartFraction h Over 20 EndFraction + 60
c = StartFraction 20 Over h EndFraction + 60
c = 20 h + 60
c = 20 + 60 h
