Answer:
Jose will pay $39
Explanation:
If the Jacket is $60 and 10% off, then after the discount it will be $60-$6 (.1x60), which is $54.
Another way to calculate the post-discount price is to take $60 x .90. If there's a 10% discount, he will pay 90% of the price or 1-.10 of the price. $60x.9 = $54. This is a very easy way to calculate what you will pay when you are shopping in a store and there's something on sale. Life skills!
$54 - $15 = $39
