Final answer:
Natalie saves $6.75 by using a 15% off coupon on a $45.00 camera, calculated by multiplying the original price by 0.15.
Step-by-step explanation:
The student's question is about calculating the amount of money saved when using a 15% off coupon on a camera that costs $45.00. To find the savings, we convert the percent to a decimal by dividing by 100, thus 15% becomes 0.15. We then multiply the original price by this decimal to determine the savings.
So, the calculation would be:
$45.00 × 0.15 = $6.75
Therefore, Natalie saves $6.75 by using the coupon.
