Answer:
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.
Square root of 1.6 is 1.265
8.2 —- 2.864
