# A bicycle has a listed price of $599.95 before tax. If the sales tax rate is 9.75%, how do you find the total cost of the bicycle with sales tax included? ##### 1 Answer Jan 13, 2017 #### Answer: See the full explanation for how to solve this problem below. #### Explanation: We can write an equation for the total cost of the bicycle as: $C = p + \left(t \times p\right)$Where: $C$is the total cost we are trying to calculate. $p$is the list price -$599.95
$t$ is the tax rate - 9.75%. "Percent" or "%" means "out of 100" or "per 100", Therefore 9.75% can be written as $9.75 \frac{x}{100}$.

Substituting and solving for $C$ gives:

C = $599.95 + (9.75/100 xx$599.95)

C = $599.95 + (($5849.5125)/100)

C = $599.95 +$58.50

$C = 658.45$
