Answer:

Step-by-step explanation:
Combine exponents by multiplying (2x3=6)
Common difference (d) = - 14-(-17)
d = -14+17
d = 3...
Tn = -17+(n-1)3
Tn = - 17+3(n-1)
Option a is correct.....
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;
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>
