Question

I don't understand 14. A, B, and C

Answer 1

14a. C = 0.09(m - 25) + 50
        C = 0.09(80 - 25) + 50
        C = 0.09(55) + 50
        C = 4.95 + 50
        C = 54.95

14b. C = 0.09(m - 25) + 50
       85 = 0.09(m - 25) + 50
     - 50                         - 50
       35 = 0.09(m - 25)
     0.09         0.09
  388⁸/₉ = m - 25
 + 25          + 25
  413⁸/₉ = m

14c. The input values that are below 25 does make any sense because it shows that the input values can make the output values decrease itself.
