When getting into shape by exercising, the subject’s maximum recommended number of
heartbeats per minute (h) can be determined by subtracting the subject’s age (a) from 220
and then taking 75% of that value. This relation is expressed by which of the following formulas?
A. h = .75(220 – a)
B. h = .75(220) – a
C. h = 220 – .75a
D. .75h = 220 – a
E. 220 = .75(h – a)

Best ResponseYou've already chosen the best response.0it says h can be determined we can say its h= by subtracting subjest age which is a from 220 it means 220  a and taking the percentage of something is to times the .percent to the value so we get h = .75(220a)
