Step-by-step explanation:
Answer: x=17
Step-by-step explanation:
7x + 15 = 4x + 66 Subtract 4x from both sides
-4x -4x
3x + 15 = 66 subtract 15 from both sides
-15 -15
3x = 51 Divide both sides by 3
x= 17
Let the selling price be S. The selling price based on selling price is found from:
Cross-multiplying, we get:
0.75S = S - 150
which when solved for S gives a selling price = $600.
To find the selling price based on cost, the following equation applies:
Cross-multiplying, we get:
112.50 = S -150
which when solved for S gives a selling price = $262.50.
