To calculate the monthly interest charge on the window display cost of $1,242 at a monthly interest rate of 1.25%, you can use the following formula:
\[
\text{Interest} = \text{Principal} \times \text{Rate}
\]
Where:
- Principal = $1,242
- Rate = 1.25% = 0.0125 (as a decimal)
Now, plug in the values:
\[
\text{Interest} = 1,242 \times 0.0125
\]
Calculating the interest:
\[
\text{Interest} = 1,242 \times 0.0125 = 15.525
\]
Rounding to two decimal places, the interest charge at the end of the first month is approximately $15.53.
So, the correct response is:
**$15.53**
\[
\text{Interest} = \text{Principal} \times \text{Rate}
\]
Where:
- Principal = $1,242
- Rate = 1.25% = 0.0125 (as a decimal)
Now, plug in the values:
\[
\text{Interest} = 1,242 \times 0.0125
\]
Calculating the interest:
\[
\text{Interest} = 1,242 \times 0.0125 = 15.525
\]
Rounding to two decimal places, the interest charge at the end of the first month is approximately $15.53.
So, the correct response is:
**$15.53**
