Question

The original price of a photo album is $24. Which coupon is a better deal? Take 50% off any purchase or $15 off any photo album

Answer 1

Recall that the y% of x can be computed using the following expression:

$x*\frac{y}{100}.$

Therefore the 50% of $24 is:

$24*\frac{50}{100}.$

Simplifying the above result we get:

$24*0.5=12.$

Now, notice that 12<15, therefore the coupon with $15 off any photo album is a better deal.

Answer: $15 off any photo album​
