Answer:
3. $ Markup = $3.50
Retail Price = $13.50
4. $ Markup = $10
Retail Price = $50
Explanation:
Turn the % markups into decimals. For 3, you would turn the % markup into 0.35 and for 4 you would turn the % markup into 0.25.
Multiply the decimals by the price. Your result for the $ markup for 3 should be $3.50 and the result for 4 should be 10.
Now add the $ markup to the original price for 3 and 4.
10 + 3.50 = $13.50
40 + 10 = $50
I hope this helped.
