The cost in dollars of bowling at the local bowling alley, f(x), including shoe rental,
is a linear function of x, the number
of games bowled. If f(x) changes by 5
when x changes by 2, what is the rate of
change of the cost in dollars with respect
to the number of games bowled?

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
