Installation fee equation will be added onto the original equation
So g = base cost + percent cost + $100
(Cost of carpet) ---> g = $7.5x + ($7.5x * 0.05) + $100

Answer: $156.25
Step-by-step explanation:
You need to find the cost of the carpet. Then, to find the service fee, take 5% of the carpet cost. After that, add 100 to that product.
Step 1: Set the value of x to the number of square feet.
x = 150
f(150) = 7.5 * 150.
Step 2: Multiply
7.5 * 150 = 1125
Step 3: Find 5% of 1125.
5% = 0.05
0.05 * 1125 = 56.25
Step 4: Add 100 to the product.
56.25 + 100 = $156.25
