Answer

Option D is correct

The least total cost is from Big Town Electronics.

Step-by-step explanation

We need to find the store that would result in the least total cost for Michelle.

Big Town Electronics

Price = $120

Discount = 10% off

Total Cost = (Price) - (Discount)

= 120 - (10% × 120)

= 120 - (0.10 × 120)

= 120 - 12

Total Cost = $108

Central Phones

Price = $120

Discount = $10 off

Total Cost = (Price) - (Discount)

= 120 - (10)

= 120 - (10)

Total Cost = $110

Main Street Mobile

Price = $160

Discount = 30% off

Total Cost = (Price) - (Discount)

= 160 - (30% × 160)

= 160 - (0.30 × 160)

= 160 - 48

Total Cost = $112

Phone Forum

Price = $125

Discount = $16 off

Total Cost = (Price) - (Discount)

= 125 - (16)

= 125 - 16

Total Cost = $109

Wireles Inc

Price = $110

Discount = No discount

Total Cost = (Price) - (Discount)

= 110 - (0)

= 110 - 0

Total Cost = $110

We can then write the total cost for each of the stores now

Big Town Electronics = $108

Central Phones = $110

Main Street Mobile = $112

Phone Forum = $109

Wireless Inc = $110

We can easily see that the least total cost is from Big Town Electronics.

Hope this Helps!!!
