Question

Dora bought a bottle of nail polish that was marked down by 20 percent from its original price of $4.50. Including a 9 percent sales tax, what is the final cost of the bottle of nail polish?

Answer 1

Answer:

Hey there!

Marked down by 20 percent is equal to 80 percent of the original value.

9 percent sales tax

3.6(1.09)=3.92
