Answer:
The price before tax was $110
Step-by-step explanation:
Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b: b + 0.175b = $129.25. Combining the b terms, we get:
1.175b = $129.25. Solving for b by dividing both sides by 1.175, we get
b = $110. The price before tax was $110.
