Madelyn and her children went into a movie theater and she bought $39 worth of bags of popcorn and pretzels. Each bag of popcorn
costs $6.50 and each pretzel costs $3.25. She bought 4 times as many pretzels as bags of popcorn. Graphically solve a system of equations in order to determine the number of bags of popcorn, x,x, and the number of pretzels, y,y, that Madelyn bought.

Answer:
Her proximate APR is 5.1%
Step-by-step explanation:
The formula of the APR is ×
× 100%, where
- FC is the finance charge
- A is the amount financed
- m is the number of months
∵ Whitney bought a watch for $107.5
∴ A = 107.5
∵ The finance charge was $11
∴ FC = 11
∵ She paid for it over 6 months
∴ m = 6
- Substitute these values in the formula above
∵ ×
× 100%
∴ APR = 5.11627907%
- Round it to the nearest tenth
∴ APR = 5.1%
Her proximate APR is 5.1%
