Answer:
The interest earned in a year was $1080.
Step-by-step explanation:
Since the money was invested at a simple interest rate, then the amount earned in one year is given by the following formula:
M = C*r*t
Where M is the amount earned, C is the amount invested, r is the rate of interest and t is the time elapsed. Applying the data from the problem, we have?
M = 20000*(5.4/100)*1
M = 20000*0.054
M = 1080
The interest earned in a year was $1080.

The total amount Sarah end up saving after reducing her debt and paying us our fee is $2,500.
<h3>Percentage</h3>
- Percentage reduction = 50%
Amount of reduction = 50% × $10,000
= 0.5 × 10,000
= $5,000
Cost of services = 25% of $10,000
= 25/100 × 10,000
= 0.25 × 10,000
= $2,500
Total savings = Amount of debt - Amount of reduction + Cost of services
= 10,000 - 5,000 + 2,500
= $2,500
Therefore, the total amount Sarah end up saving after reducing her debt and paying us our fee is $2,500.
