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 + (t xx p)

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 9.75x/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
