Kristina joined a health club. she paid an annual membership fee of $40 and $3.50 each time she worked out.
part a
write an equation to show the total amount, t, kristina paid to go the health club z times.
part b
kristina spent a total of $110.00 before she stopped going to the health. how many times did she go to the health club?

Part A) The equation is

Part B) Kristina did go to the gym 20 times

Step-by-step explanation:

Let

t-----> the total amount

z----> the number of times that Kristina go the health club

Part A) Write an equation

we know that

The linear equation that represent this situation is

Part B) For

Substitute the value of t in the linear equation and solve for z

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
