Answer provided by our tutors
let
x = the price of one blouse
y = the price of one skirt
Carol bought 5 blouses and 3 skirts for a total of $215
5x + 3y = 215
Ellen bought 3 blouses and 2 skirts for a total of $135
3x + 2y = 135
by solving the system of equations
5x + 3y = 215
3x + 2y = 135
we find
x = $25
y = $30
the price of the blouse is $25.
the price of the skirt is $30.
