Answer:
$409.86
Explanation:
230 is the before markup
We must apply the markup (or even discount) before the tax is applied.
Marked up 65% means we must do .65(230) <---This will tell us how much more the tent is going to sell for
.65(230)=149.5
So we started with 230 and it is going up by 149.5, so the new price before tax is 230+149.5=379.5
Now the tax is applied to what you are paying (before tax).
So 8% of 379.5 is .08(379.5)=30.36
So new price + tax is the total cost
379.5 +30.36
=409.86
