Answer:
$252
Step-by-step explanation:
The TV, which cost $400, is on sale for 30% off. So, let's find the price.
0.30 × 400 = 120
400 - 120 = 280
The TV is on sale for $280. But, there is also 10% off the sale price since it was a floor model. So,
0.10 × 280 = 28
280 - 28 = 252
The price of the TV before taxes is $252.
This is not the same as 40% off because that would make the price of the TV $240.
0.40 × 400 = 160
400 - 160 = 240
Hope that helps.
