Question

for the following situation, find the average monthly expense that you would use in budgeting for the given expense. note: annual means once a year, and semiannual means twice a year.
sara pays $5000 for tuition and fees for each of the two semesters, plus an additional $260 for textbooks each semester.
the average monthly cost for tuition and fees and textbooks is $□
(round to the nearest dollar as needed.)

Explanation:

Step1: Calculate total annual cost

Total tuition and fees: \(2\times5000 = 10000\) dollars.
Total textbooks cost: \(2\times260=520\) dollars.
Total annual cost \(C = 10000 + 520=10520\) dollars.

Step2: Calculate average monthly cost

Since there are \(n = 12\) months in a year, the average monthly cost \(M=\frac{C}{12}\).
Substitute \(C = 10520\) into the formula: \(M=\frac{10520}{12}\approx877\) dollars.

Answer:

\(877\)
