let
w = the number of white sweatshirts sold
y = the number of yellows sweatshirts sold
One day a store sold 23 sweatshirts:
w + y = 23
In all, $254.35 worth of sweatshirts were sold:
9.95w + 12.50y = 254.35
by solving the system of equations:
w + y = 23
9.95w + 12.50y = 254.35
we find:
w = 13 white sweatshirts
y = 10 yellow sweatshirts
