To write an equation, we will need to pick a variable to represent the cost of the CD. How about c?

Yeah that works

Cool. So the total cost will be the cost of the cd plus the tax. Do you know how to find the amount of tax?

using the variable, c?

No

joannablackwelder · Answer

The amount of tax can be found by multiplying the cost of the cd by the tax as a decimal.

We are trying to find 5% of the price. So, for example, if the price were $10, we would multiply that by .05 to find the amount we would pay for tax. Make sense?
