Answer provided by our tutors
let
w = the number of white sweatshirts sold
y = the number of yellow sweatshirts sold
one day a store sold 21 sweatshirts:
w + y = 21
white ones $9.95 and yellow ones cost $11.50. In all 226.00 worth of sweatshirts were sold:
9.95w + 11.50y = 226
by solving the system of equations:
w + y = 21
9.95w + 11.50y = 226
we find:
w = 10 white sweatshirts
y = 11 yellow sweatshirts
