The interest that she will pay is $ 504.

Given : Andrea borrowed 2,240 at 15% apr for 18 months.
We have to calculate the interest will she pay.
Using formula for Simple interest.
Where P is principal amount
r is rate of interest
t is time period.
Given : P = $ 2240
t = 18 months
In years ,
r = 15% = 0.15

0.12
Step-by-step explanation:

60/100 = 0.6
0.6 * 100 = 60 have fever
20% of the people having fever (60 of them) have sore throats, so,
<u><em>What is 20% of 60?</em></u>
We convert percentage to decimal and multiply:
20/100 = 0.2
0.2 * 60 = 12 have sore throat
