Let’s solve this fun little puzzle using some equations! We can define two variables: let \( x \) be the number of drinks and \( y \) be the number of pretzels. We know two things: 1. The total number of drinks and pretzels is 12: \[ x + y = 12 \] 2. The total cost is \( \$ 44.50 \): \[ 6x + 3.25y = 44.50 \] Now, let's solve the first equation for \( y \) and substitute it into the second equation: \[ y = 12 - x \] Now plug this into the second equation: \[ 6x + 3.25(12 - x) = 44.50 \] Simplifying that gives us: \[ 6x + 39 - 3.25x = 44.50 \] \[ 2.75x + 39 = 44.50 \] \[ 2.75x = 5.50 \] \[ x = 2 \] (number of drinks) Now plug \( x \) back into the first equation to find \( y \): \[ 2 + y = 12 \] \[ y = 10 \] (number of pretzels) So, Brody bought **2 drinks** and **10 pretzels**! Brody bought \( 2 \) drinks and \( 10 \) pretzels.
