Ten small and twelve medium boxes costs $42. Five small and ten medium boxes cost 429. What is the cost for a small box?
Answer provided by our tutors
let
s = the cost of small box
m = the cost of medium box
10 small and 12 medium boxes costs $42
10s + 12m = 42
5 small and 10 medium boxes cost $429
5s + 10m = 429
by solving the system of equations
10s + 12m = 42
5s + 10m = 429
we find
m = 102
s = -118.2
