Answer 2

Jocelyn and her children went into a movie theater and she bought $75.50 worth of candies and pretzels. Each candy costs $4.75 and each pretzel costs $3.50. She bought a total of 18 candies and pretzels altogether. Determine the number of candies and the number of pretzels that Jocelyn bought.

Answer 3

Let's assume the number of candies Jocelyn bought is "x" and the number of pretzels she bought is "y."

We can create two equations based on the given information:
1. The total cost of candies: 4.75x
2. The total cost of pretzels: 3.50y

The total cost of candies and pretzels combined is $75.50, so we have the following equation:
4.75x + 3.50y = 75.50

Jocelyn bought a total of 18 candies and pretzels, so we have another equation:
x + y = 18

We can now use these two equations to solve for x and y.

Rearrange the second equation to solve for x:
x = 18 - y

Substitute this expression for x into the first equation:
4.75(18 - y) + 3.50y = 75.50

Simplify the equation:
85.50 - 4.75y + 3.50y = 75.50

Combine like terms:
-1.25y = -10

Divide both sides by -1.25:
y = 8

Substitute the value of y back into the second equation to solve for x:
x + 8 = 18
x = 10

Therefore, Jocelyn bought 10 candies and 8 pretzels.
