Question

At a concession stand, one person purchased 3 drinks and 3 soft pretzels for a total of $9.00. Another person purchased 4 drinks and 2 soft pretzels for a total of 8.50. What was the price of one soft pretzel

Answer 1

First we define the variables:
x: price in $ for each drink
y: price in $ for each soft pretzel.
We write the system of equations:
3x + 3y = 9
4x + 2y = 8.50
We solve the system:
x = 1.25 $
y = 1.75 $
(See attached image)
Answer:
The price of one soft pretzel is:
y = 1.75 $
