Multiply the hours of labor by $55, then add $80. if c = cost in dollars and h = hours of labor, which equation expresses the rule above? a. c(h) = 80h 55 b. c(h) = 55(h 80) c. c(h) = 55h 80 d. c(h) = 80(h 55)

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
