Question

a sofa sold at four different stores has a retail price of $1,200. each store is offering a different promotion.

• store a: 10% off sale
• store b: $100 off coupon
• store c: $75 off coupon
• store d: $150 rebate

which offers the best deal?

Explanation:

Step1: Calculate Store A's price

10% off means we pay 90% of the original price. So, $1200\times(1 - 0.10)=1200\times0.90 = 1080$.

Step2: Calculate Store B's price

Subtract the $100 coupon: $1200 - 100 = 1100$.

Step3: Calculate Store C's price

Subtract the $75 coupon: $1200 - 75 = 1125$.

Step4: Calculate Store D's price

Subtract the $150 rebate: $1200 - 150 = 1050$.

Step5: Compare the prices

Store A: $1080, Store B: $1100, Store C: $1125, Store D: $1050. The lowest price is from Store D.

Answer:

Store D: $150 rebate
