To calculate the total interest on a simple interest loan, you can use the formula:
\[ \text{Interest} = P \times r \times t \]
where:
- \( P \) is the principal amount (the initial amount borrowed),
- \( r \) is the yearly interest rate (as a decimal), and
- \( t \) is the time in years.
In this case:
- \( P = 70,000 \)
- \( r = 5% = 0.05 \)
- \( t = 15 \)
Plugging in the values:
\[ \text{Interest} = 70,000 \times 0.05 \times 15 \]
Calculating this step-by-step:
-
Calculate \( 70,000 \times 0.05 \): \[ 70,000 \times 0.05 = 3,500 \]
-
Then multiply that result by 15: \[ 3,500 \times 15 = 52,500 \]
Thus, the total interest Tonya will end up paying the bank is $52,500.
The correct answer is: A. $52,500
