Final answer:
Jeanne would save $1.51 by choosing the store brand laundry detergent over the name brand with a $1.95 coupon.
Step-by-step explanation:
To determine how much Jeanne would save by purchasing the store brand laundry detergent instead of using her coupon for the name brand, we need to consider the normal cost of the name brand detergent, the discount provided by the coupon, and the cost of the store brand detergent.
The normal cost of the name brand laundry detergent is $14.99. If Jeanne uses a coupon for $1.95 off, she would pay $14.99 - $1.95 = $13.04 for the name brand detergent.
The store brand cost is $11.53. To find the savings by purchasing the store brand instead of the name brand with the coupon, we subtract the store brand cost from the discounted name brand cost: $13.04 - $11.53 = $1.51.
Therefore, Jeanne would save $1.51 if she buys the store brand laundry detergent instead of using her coupon on the name brand.
