Problema Solution
Katie has 35 cups of flower. She makes cookies that require 3/8 cup of flower for each cookie. If she makes as many cookies as she has flower, how much flower will be left over?
Answer provided by our tutors
Let 'x' represent the number of cookies made, x is integer.
(3/8)x <= 35 multiply both sides by 8/3
x <= 35*(8/3)
x <= 93.33
She can make 93 cookies at most.
The flower left is: 35 - 93*(3/8) = (280 - 3*93)/8 = 1/8 cup of flower.
