If 15lb of tea and 10lb of coffee together cost $15.50, while 25lb of tea and 13lb of coffee at the same prices cost $24.55, find the price per pound of each.
Answer provided by our tutors
let
t = the cost of 1 lbs of tea
c = the cost of 1 lbs of coffee
15lb of tea and 10lb of coffee together cost $15.50
15t + 10c = 15.50
25lb of tea and 13lb of coffee at the same prices cost $24.55
25t + 13c = 24.55
by solving the system of equations
15t + 10c = 15.50
25t + 13c = 24.55
we find
t = $0.8
c = $0.35
