Step-by-step explanation:

As given

You are making several purchases from the B-Better Electronics store.

You can buy from this store online or in a physical store.

For physical store

1 pair of headphone cost $14.99 for each .

1 DVDs cost $13.95 for each .

1  CDs cost $9.85 for each .

Total cost of purchasing from  the physical store =  cost  of 1 pair of headphone + cost of 4DVDs + cost of 2CDs

                                                    = $14.99 + 4 × $13.95 + 2 × $9.85

                                                    = $14.99 + $55.8 + $19.7

Total cost of purchasing from  the physical store = $ 90.49

As given

You have a coupon for 20% off that can only be used in the physical store .

20% is written in the decimal form.

= 0.20

Discount price = 0.20 × Total cost of purchasing from  the physical store

                         = 0.20 × 90.49

                         = $18.098

Total cost of purchasing from  the physical store after discount = Total cost of purchasing from  the physical store - Discount price

                                                                        = $90.49 -  $18.098

                                                                        = $ 72.392

As given

The sales tax of 7.5% only applies to the physical store.

7.5% is written in the decimal form.

= 0.075

Salex tax price = 0.075 × Total cost of purchasing from  the physical store after discount

                        = 0.075 × 72.392

                        = $ 5.4294

Total amount of money pay at the physical store =  Total cost of purchasing from  the physical store after discount + Sales price

                                                                                 = $ 72.392 +  $ 5.4294

                                                                                 = $77.82 (Approx)

Therefore the total amount of money pay at the physical store is  $77.82 .

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
