You can buy #5# cups of food to feed the animals before running out of money.

We can just count up how many cups we can purchase to accomplish this easily. #"starting balance" = $12.50# #"after cup " 1 = 12.5 - 2.5 = color(blue)($10.00# #"after cup " 2 = 10 - 2.5 = color(blue)($7.50# #"after cup " 3 = 7.5 - 2.5 = color(blue)($5.00# #"after cup " 4 = 5 - 2.5 = color(blue)($2.50# #"after cup " 5 = 2.5 - 2.5 = color(blue)($0.00# From this, we can see that after buying the #5^"th"# cup, the buyer is out of money, so that means that you can buy #5# cups of food to feed the animals before running out of money.

Pay the entry fee and use the remaining money to buy #2# cups of food.

The entry fee is #$7.50# and once you have paid that, you can use the remaining money to buy cups of food. Pay the entry fee: #$12.5-$7.5 = $5# #$5 div $2.50 = 2# cups of food can be bought.
