Recall that the y% of x can be computed using the following expression:
[tex]x*\frac{y}{100}.[/tex]Therefore the 50% of $24 is:
[tex]24*\frac{50}{100}.[/tex]Simplifying the above result we get:
[tex]24*0.5=12.[/tex]Now, notice that 12<15, therefore the coupon with $15 off any photo album is a better deal.
