Why do I think you're asking us to do your homework? When you see the word "off," that is what you're NOT paying. Then you have to find out what you ARE paying, so subtract the percentage "off" from 100 and multiply the original cost of the item by your answer, indicated in decimal form rather than percentage. (1.00 - .28 = .72. Your answer will be 49.95 x .72 = 35.964, or $35.97). Number 5 is done differently. Find the interest by converting the percentage to a decimal form again, multiply it by $500. That gives you the interest for ONE month. Guess what you have to do to find the answer for 15 months! OY VAY!!

No.
However, here's how you do it:
$100 dog bone, 15% off
$100 * 0.15 = $15
$100 - $15 = $85
So the price is $85
