Answer:
Interest rate, R = 244%
Step-by-step explanation:
Given the following data;
Principal = $270
Simple interest = future amount - principal = 309.60 - 270 = $39.60
Time = 22/360 = 0.06 years
To find the interest rate?
Mathematically, simple interest is calculated using this formula;
Where;
- S.I is simple interest.
- P is the principal.
- R is the interest rate.
- T is the time.
Substituting into the equation, we have;
Cross-multiplying, we have;
<em>Interest rate, R = 244.44 ≈ 244%</em>
<em>Therefore, the pawnbroker charged Elisa a simple interest rate of 244%.</em>
Hi!
We can set up a proportion to solve this
Cross multiply
3 x 16 = 48
