4b+2c=36, solve for b, subtract 2c from both sides

4b=36-2c divide both sides by 4

b=9-0.5c

Then we are told that:

7b+3c=59, using b=9-0.5c we get:

7(9-0.5c)+3c=59 perform indicated multiplication on left side

63-3.5c+3c=59 combine like terms on left side

63-0.5c=59 subtract 63 from both sides

-0.5c=-4 divide both sides by 0.5

c=8

So each souvenir cup costs $8.

(and each bag of cotton candy is $5)
