Answer:
$14.034
Explanation:
40/10 means that the price has a 40% discount and then, a 10% discount from what is left. To calculate the net price, first you have to calculate the price with the 40% discount:
25.99*(1-0.4)= 15.594
Then, you have to calculate the price with the 10% discount:
15.594*(1-0.1)= 14.034
According to this, the net price is $14.034.
