104. During exercise, the recommended maximum heart rate in beats per minute is modeled by the formula M = 176 – 0.8A, where M is the maximum heart rate and A is the person’s age. Solve the formula for A. At what age would you have a recommended maximum heart rate in beats per minute of 160?
M = 176 – 0.8A
0.8A =176 – M
A = 220 – 1.25M

Given: M=160
A = 220 – 1.25*160 = 220 – 200 = 20
