To calculate how much Mary will save using the deal versus paying the full price for all 4 tires, we can follow these steps:
1. Calculate the full price for all 4 tires:
Full price = $200 per tire * 4 tires = $800
2. Calculate the discount on the 4th tire using the deal:
Discounted price = 75% off * $200 = $150
3. Calculate the total price with the discount:
Total price with discount = Full price - Discounted price for 4th tire
= $800 - $150
= $650
4. Calculate the sales tax amount:
Sales tax = 8% of Total price with discount
= 8% * $650
= $52
5. Calculate the final amount Mary will pay:
Final amount = Total price with discount + Sales tax
= $650 + $52
= $702
6. Calculate the amount she saved:
Amount saved = Full price - Final amount
= $800 - $702
= $98
Therefore, Mary will save $98 by using the deal compared to paying the full price for all 4 tires.
