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
