chris paid $36 for 3 tank tops and 2 t-shirts. a t-shirt cost 3 times as much as a tank top. how much did chris pay for the 2 t-shirts?
Answer provided by our tutors
Let
'x' = the price of one tank top
'y' = the price of one t-shirt
chris paid $36 for 3 tank tops and 2 t-shirts:
3*x + 2*y = 36
t-shirt cost 3 times as much as a tank top
y = 3*x
By solving the system of equation
3*x + 2*y = 36
y = 3*x
we find
x = $4
y = $12
The cost of 2 t-shirts is
2*y = 2*12 = $24
