Question

A cricket bat costs $129.25 after tax has been added on at 17.5%. How much did the cricket bat costs before tax was added

help

Answer 1

The price before tax was $110

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.
