A store offers a rewards program where shoppers earn 1 point for every $5 they spend plus 100 bonus points on their first purchase. If function f represents the number of points earned as a function of the total amount spent x, which function represents the total amount spent as a function of the number of points earned?

The expression that represents the total amount spent as a function of the number of points earned is x = y*5 - 500. This function is only valid for 100 or plus points, since that is the minimum amount of one can have after a purchase.

Step-by-step explanation:

To solve this problem we will first calculate the function that relates the number of points earned and the total spent x. This is given by:

y = f(x) = 100 + x/5

In order to calculate the function that represents the total spent as a function of points earned we need to isolate the variable x, in the expression above. We have:

y = 100 + x/5

y - 100 = x/5

x/5 = y - 100

x = y*5 - 500

The expression that represents the total amount spent as a function of the number of points earned is x = y*5 - 500. This function is only valid for 100 or plus points, since that is the minimum amount of points one can have after a purchase.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
