5 c + 2 t = 18
3 c + 8 t = 55
multiply first eqn by 4
20c + 8 t = 72
3 c + 8 t = 55
------------------------- subtract
17 c = 17
c = $ 1.00
etc
3 c + 8 t = 55
multiply first eqn by 4

3 c + 8 t = 55

Multiply first equation by 4, then subtract second equation from the first.
You should be able to take it from there.
