The baker formula estimates the maximum heart rate, in beats per minute, of a person who is
a years old. the formula is shown below:
b(a) = 200 -0.75a
at what age is the maximum heart rate 188 beats per minute?

For a=16, the Maximum Heart Rate is 188 Beats Per Minute.

Step-by-step explanation:

To begin, we know that the formula:

   Eqn(1).

is equivalent to a linear equation of algebraic form denoted as:

                 Eqn(2)

as such that  Eqns (1) and (2) relate as follow:

⇔ : denoting our Dependent Variable, in this case Max. Heart Rate in Beats Per Minute

⇔ : is our Independent Variable, in this case the Age of the Person

⇔ : denoting the Rate of Change of the Age.

⇔ : denoting our Constant.

Now in the question our value of is given as 188 beats per minute, which by plugging in Eqn(1) gives:

from which we can solve to obtain the value of as follow:

         Gather similar terms on each side

                  Simplify

                          Solve for

Which tells us that at the Age of 16, the Max. Heart Rate is 188 Beats Per Minute.
