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
Andreyy89

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.

Let x be the total number of questions. We know that Jess answered correctly 35 of them, and those 35 are the 74.47% of all questions.

So, can build the proportion linking the correct answers to the total number of questions:

35\div x = 74.47\div 100

Solving for x, we have

x = \dfrac{3500}{74.47}\approx 47
