Answer:
y=11
Step-by-step explanation:
To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.
To Check your answer:
Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.
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.
