Question

In a football game, Brandon bought one cotton candy and one popcorn for a total of $25. Jonathan bought 2 cotton candies and 3 popcorns. Jonathan spent a total of $57, how much does each cotton candy cost?

Answer 1

Let "c" be the price of a cotton candy and "p" be the price of a popcorn.

Then, for Brandon, c + p = 25

And for Jonathan, 2c + 3p = 57

Using Brandon's equation, we can subtract c from both sides to get p = 25 - c

Then, in Jonathan's equation, we can substitute "25 - c" wherever we see "p" because "p" equals "25 - c":

2c + 3(25 - c) = 57

2c + 75 - 3c = 57

-c + 75 = 57

-c = -18

c = 18

So the cotton candy costs $18 each
