t + c = 36 (tomatoes + corn = 36 cans
.80t + .40c = 18 (80 cents per can for tomatoes + 40 cents Per can for corn = 18)

those are the 2 equations needed to solve this problem. We can now solve by substitution.
t + c = 36
t = 36 - c
now sub 36 - c in for t in the other equation.
.80t + .40c = 18
.80(36 - c) + .40c = 18

now, can you finish and solve for c ??
