Question

Roses normally cost $19.00 a dozen, but for Valentine's Day the price goes up to $35.00. What is the difference in price, including 7% tax?

Answer 1

$17.12

Explanation:

First let's find the normal cost with tax

7/100*19=133/100=$1.33

$19+$1.33=$20.33

Now we find the cost with tax for the Valentine's Day price

7/100*35=$2.45

$35+$2.45=$37.45

Now we subtract the normal cost from the Valentine's Day price

$37.45-$20.33=$17.12
