EXPLANATION

Let's see the facts:

Machine price = $220.00

Sales tax=7%

At Store A-----> Discount=15%

At Store B----->Coupon for $35

Part I:

Sale price at Store A (including discount)= Machine Price*[100%-Discount] (In decimal form)

Sale price at Store A (including discount)= 220.00 * 0.85 = $187

Part II:

Sale price at Store A (including tax) = Sale price at Store A (including discount) + Sale price at Store A (including discount)* Tax in decimal form

Sale price at Store A (including tax) = 187 + 187*0.07 = $200.09

Part III:

Sale price at Store B (including coupon)=Machine Price-coupon discount

Sale price at Store B (including coupon)=220-35 = $185

Part IV

Sale price at Store B (including tax) = Sale price at Store B (including coupon) + Sale price at Store A (including coupon)* Tax in decimal form

Sale price at Store B (including tax) = 185 + 185*0.07 = $197.95

Part V:

Assuming that Maxine wants to spend the least amount of money as possible, he should buy the fax machine at Store B.

Answers:

Part I: $187

Part II: $200.09

Part III: $185

Part IV: $197.95

Part V: Store B
