Determine the approximate monthly cost of spending $24.85 on tutoring at least 5 times a week. (Assume four weeks in a month.)
The correct answer and explanation is:
Let’s break down the problem step-by-step:
Step 1: Identify the cost per tutoring session
- Each tutoring session costs $24.85.
Step 2: Determine the number of tutoring sessions per week
- The person tutors at least 5 times a week.
- For calculation, assume exactly 5 times per week.
Step 3: Calculate weekly cost
- Weekly cost = cost per session × number of sessions per week
- Weekly cost = $24.85 × 5 = $124.25
Step 4: Calculate monthly cost
- Assume 4 weeks in a month.
- Monthly cost = weekly cost × 4
- Monthly cost = $124.25 × 4 = $497.00
Final answer:
The approximate monthly cost of tutoring at least 5 times a week at $24.85 per session is $497.00.
Explanation (300 words):
To calculate the monthly expense for tutoring, we first consider the cost per individual session. Here, one session costs $24.85. Since the person tutors at least 5 times a week, we multiply the cost of one session by the number of sessions per week to get the weekly cost. Specifically, 5 sessions × $24.85 each = $124.25 per week.
Next, because a month typically consists of about four weeks, we multiply the weekly cost by 4 to estimate the monthly total. Doing this yields $124.25 × 4 = $497.00.
This straightforward multiplication approach assumes the minimum number of sessions per week (5) and exactly 4 weeks per month, which simplifies the calculation while providing a reasonable monthly cost estimate.
If tutoring happens more than 5 times a week, the monthly cost will be higher. Also, some months have slightly more than 4 weeks (about 4.3 weeks on average), which could slightly increase the monthly cost, but for budgeting, four weeks is a common assumption.
Understanding these basic multiplication steps helps in financial planning, ensuring you allocate sufficient funds for recurring expenses such as tutoring. This calculation is helpful whether you are budgeting for yourself, helping a student, or managing tutoring business expenses.
