Answer:
The total amount of money pay at the physical store is $77.82 .
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 .
