Teresa bought 4 CDs that were each the same price. Including sales tax, she paid a total of 53.60 . Each CD had a tax of 0.80 . What was the price of each CD before tax?

Each CD was $10.20 before sales tax.

Step-by-step explanation:

Well, I've divided 53.60 by 4, then I subtracted the sales tax out.

Therefore, you get the answer.

13.4-3.2=10.2

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
