Answer

Explanation:

Step1: Calculate the marked - up price

The marked - up price is the original price plus the markup amount. The markup amount is 25% of the original price. The original price is $8.80. The markup amount is $8.80\times0.25 = 2.2$. So the marked - up price is $8.80 + 2.2=8.80\times(1 + 0.25)=8.80\times1.25 = 11$.

Step2: Calculate the total cost with sales tax

The sales tax is 3% of the marked - up price. The sales tax amount is $11\times0.03 = 0.33$. The total cost is the marked - up price plus the sales tax, so it is $11+0.33 = 11\times(1 + 0.03)=11\times1.03=11.33$.

Answer:

$11.33$
