X = 5!

4x+1=2x+11
-1 -1 (Subtract 1 from both sides)
4x =2x+10
-2x -2x (Subtract 2x from both sides)
2x = 10
—— ——
2x 2x (Divide both sides by 2x)

X = 5

1. Mrs. Nelson wants to buy a wireless speaker for her son. She has narrowed down her choice to two stores:
Oksi-84 [34.3K]

a) Mrs. Nelson will pay $45 for the speaker at Kohl's.

b) Mrs. Nelson would pay $43.70 for the speaker at Target.

c) Mrs. Nelson would get the best deal from Target's.

Step-by-step explanation:

Selling price at Kohl = $60.00

Discount coupon = 25%

Purchase price of Target = $38.00

Mark up = 15%

a.) How much would Mrs. Nelson pay for the speaker at Kohl’s?

Discount = 25% of selling price

Discount amount = \frac{25}{100}*60=\frac{1500}{100}

Discount amount = $15

Cost after discount = Selling price - Discount amount

Cost after discount = 60-15 = $45

Mrs. Nelson will pay $45 for the speaker at Kohl's.

b.) How much would Mrs. Nelson pay for this speaker at Target?

Mark up = 15% of purchase price

Mark up amount = \frac{15}{100}*38=\frac{570}{100}

Mark up amount = $5.70

Price after mark up = Purchase price + Mark up amount

Price after mark up = 38.00+5.70 = $43.70

Mrs. Nelson would pay $43.70 for the speaker at Target.

c.) Which store would Mrs. Nelson get the best deal and by how much?

Difference between prices = 45-43.70 = $1.30

Mrs. Nelson will save $15 on Kohl's and she will get the speaker at $43.70 at Target's, therefore, she would save $1.30 more if she buys speaker from Target's.

Mrs. Nelson would get the best deal from Target's.
