Answer:

the corn on the cobs cost $9 and the hamburgers cost $25 so the total cost is $34

Step-by-step explanation:

c = 2 because Carmel apples cost 2 dollars and c represents $2

corn on the cobb: 2 + 1 = 3 mark is buying 3 corns so 3+ 3+ 3=9

hamburgers: 2 + 3 = 5. mark is buying 5 hamburgers so 5+5+5+5+5=25

25 + 9 = 34
