I don't know what you are asking but my best guess is it will be
$4.46 in total
You simply divide 3 into 8, which results in 0.375. Now you add 7 to it, which is 7.375.
After discount: $418; total (including tax): $388.74
There are 7 sides available.
The fundamental counting principal tells us to find the total number of combinations of independent items, multiply the number of choices from each one (choices x choices x....)
This means that drink x sides x sandwiches = 560. We know there are 16 sandwiches and 5 drinks. Let S be the number of sides:
15(6)(S) = 560
80S = 560
Divide both sides by 80:
80S = 560/80
S = 7
the answer is 10 hoped this helped have a great day
