Mrs. Donelly drew the triangle above on the chalkboard and asked her students to write down possible side lengths for a, b, and
c. Edward wrote down that a = 8, b = 15, and c = 17.
Louis wrote down that a = 2, b = 4, and c = 6.
Which student's answer is correct and why? What could the side lengths be changed to on the incorrect response in order to make it a correct answer?
The answer is C) $30.00.
First, find out how much 1lb costs. 1lb would cost 1/4 of 4lb.
$10×1/4=$2.50/1lb.
So 12 pounds would be 12x the cost of 1lb.
$2.50×12 pounds=$30/12lb.
