Answer:
$19.26 or $19.
Step-by-step explanation:
Sold DVD for 50% more of the purchase price of $12, so:
12 + 50/100 * (12) = 12 + 6 = 18.
The customer will pay 7% tax on $18.
18 * (1.07) = $19.26
You would have to do 24.85 x 4 because the 24.85 is per hour and if someone is going for 4 hours, this is what we would have to work out. So it would equal: 99.40 miles per hour. :)
S = b + 15
s = skirt
b = blouse
The skirt is $15 more than the blouse
