you want to buy a newly released CD . the CD costs $17. plus 6percent tax. write an expression that represents how much money in dollars you need to buy the CD . evaluate the expression
cost = 17 + 17*0.06
you do the math
To calculate the total cost of buying the CD, including tax, we need to add the cost of the CD itself to the tax amount.
Step 1: Calculate the tax amount:
Tax Amount = CD Cost x (Tax Rate / 100)
Tax Amount = $17 x (6 / 100)
Step 2: Add the tax amount to the CD cost:
Total Cost = CD Cost + Tax Amount
Total Cost = $17 + Tax Amount
Now let's evaluate the expression:
Tax Amount = $17 x (6 / 100)
Tax Amount = $17 x 0.06
Tax Amount = $1.02
Total Cost = $17 + $1.02
Total Cost = $18.02
So, the expression evaluates to $18.02.
To calculate the total amount of money needed to buy the CD, we need to consider the cost of the CD itself and the tax.
The expression can be represented as follows:
CD Cost + (CD Cost * Tax)
Given that the CD costs $17 and the tax is 6%, we can substitute these values into the expression:
$17 + ($17 * 0.06)
Calculating the expression:
$17 + ($1.02) = $18.02
Therefore, the total amount of money, in dollars, needed to buy the CD is $18.02.
