A-REI.3 Suppose a friend tells you she wants to buy a bicycle with a price of $3749.99, and you’d like to know the bicycle’s total price (the price after taxes) so that you can compare prices at in other counties.. Find the total price, p, of the bicycle if your friend bought the bicycle in a location where the rate is r. Assume r is the rate in decimal form.


Write the equation for the situation then solve it for r.

Answer 1

The total price of the bicycle in Pierce county is $4136.24

An equation shows the relationship between two or more variables and numbers.

Let P represent the total price after taxes. The tax rate is 10.3% and the price of the bicycle is $3749.99. Hence:

Tax = 10.3% of $3749.99 = 0.103 * 3749.99 = $386.25

The total price (P) is:

P = $3749.99 + Tax = $3749.99 + $386.25

P = $4136.24

Therefore, the total price of the bicycle in Pierce county is $4136.24
