The annual interest rate is 21%
<h3>How to determine the
annual interest rate?</h3>
The given parameters are
Loan Amount, P = $300
Interest, I = $63
Number of years, T = 1
The annual interest rate is calculated as
I = PRT
Substitute the known values in the above equation
63 = 300 * R * 1
Evaluate the product
300R = 63
Divide through by 300
R = 21%
Hence, the annual interest rate is 21%

The final answer of the price of the shirt is 12
Answer:
85 cents
Step-by-step explanation:
Let a represent the price of pineapples
Let p represent the price of peaches
74p + 9a= 14p + 21a
p = 17 cents
Substitute 17 for p
74(17) + 9a = 14(17) + 21a
1258+9a= 238+21a
1258-238= 21a-9a
1020= 12a
a= 1020/12
a= 85
Hence the price of pineapples is 85 cents
