Four pair of jeans and three shirts cost $200. The price of the jeans is 5 less than twice the price of the shirt. Find the price of each.
Answer provided by our tutors
let
j = the cost of a par of jeans
s = the cost of a shirt
4 pair of jeans and 3 shirts cost $200
4j + 3s = 200
the price of the jeans is 5 less than twice the price of the shirt
j = 2s - 5
by solving the system of equations
4j + 3s = 200
j = 2s - 5
we find
j = $35
s = $20
