Answer:
$88
If this is incorrect, let me know and I will redo the problem. My answer might also be incorrect if the 0.08 you mention in the question is a percentage and not eight cents.
Explanation:
To solve this, I like to write down the numbers first.
1,100 dollars for the painting
I assume that the 0.08 is money, and not a percentage. If this is a percentage, please let me know and I will write out a new answer.
0.08+1=1.08
This is the amount paid for each dollar.
1.08Ă—1,100=1,188
Now subtract.
1,188-1,100=88
The sales tax is $88.
