Question

Jeanette has $50. Each week she loses $15. After some time, her final balance is $20. Find the amount of time she has saved money.

Amount of time:
(a) 2 weeks
(b) 3 weeks
(c) 4 weeks
(d) 5 weeks

Answer 1

Jeanette has saved money for 2 weeks, as she had $50 initially and ended with $20, losing $15 each week. The calculation is $30 total money lost divided by $15 weekly loss equals 2 weeks.

Step-by-step explanation:

The student's question is about finding the amount of time Jeanette has been saving money if she starts with $50, loses $15 each week, and ends up with $20. We can solve this problem using a simple subtraction and division approach.

First, let's calculate the total amount of money lost:

• 
  
• $50 (initial amount) - $20 (final amount) = $30 (total money lost)

Next, we divide the total money lost by the weekly loss to find the time duration:

• 
  
• $30 (total money lost) ÷ $15 (weekly loss) = 2 weeks

Therefore, Jeanette had been saving money for 2 weeks before her balance reached $20.
