A right triangle has legs of lengths 12 and 9 inches. Find the length of the hypotenuse (nearest tenth).

First convert 75% to a number by moving the decimal place to the left two places. That gives us .75. Now to figure out what 75% of $8 is we multiply .75 by 8. You should end up with $6. Now you subtract the discounted price from the original and it gives you $8-$6=$2.
