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
This is simple simplifying. If you need an explanation dm me.
here is the answer
x=-5
The unit rate in this scenario is the number of ounces per steak/in one steak.
72 oz/2 steaks= 36 oz per steak
Final answer: 36 oz per steak
