Step-by-step explanation:
Model:
s = slices
x = pizzas ordered
s = .8(.45x) + .12(.55x)
Now plugin 20 for x and you will get the total number of slices.
s = .8(.45x) + .12(.55x)
s = .8(.45(20)) + .12(.55(20))
s = 204 slices
Note, we could make this model different and smaller but I chose this method because it demonstrates what is going on with the word problem
Each peice is 1.5 inches
7*1.5=10.5
The dowel was 10.5 inches long
The answer is C i’m pretty sure because you can divide y by 15 and get x
72 because 63 + 9 is basically 9×8
around 13% chance
