Using proportions, it is found that the Customer Acquisition Cost was of $1,215.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, the customer acquisition cost is the spending in sales divided by the number of customers added.
80 customers were added, considering costs of 1200 + 9000 + 87000 = $97,200, hence:
97200/80 = $1,215.

Answer:

Step-by-step explanation:
The surface area of the prism consists of four rectangles and two trapezoids. The sum of the areas of these polygons will give the total surface area of the prism:
Rectangle 1 (top base): 
Rectangle 2 (bottom base): 
Trapezoids 1 and 2 (lateral): 
Rectangles 3 and 4 (lateral): 
Thus the total surface area is equal to
3/5(20) -3/5(15x) + 8x = 13
12 - 9x + 8x = 13
-x = 13-12
-x = 1
x = -1
