Answer:
-56c+ 30
Step-by-step explanation:
4c + 10(3 – 6c)
Rearrange terms
4c + 10(3 – 6c)
4c+10(-6c+3)
Distribute
4c+10(-6c+3)
4c-60c+30
Combine like terms
4c-60c+30
-56c+30
Common factor
-2(28c-15)
Distribute
-2(28c-15)
-56c+30
Solution:
-56c+30
Answer: Right angles
Step-by-step explanation:
let's make p stand for popcorn and d for drinks. Using those variables, we can create our equations:
2p + 3d = 18.25
4p + 2d = 27.50
From this, we can use substitution or elimination to solve:
For substitution, in the second equations, we could factor out a 2, divide both sides by 2, and then move the left over 2p to the other side to isolate d to put into the first equation.
For elimination, we can multiply the first equation by -2 so that we can remove the 4p and focus on solving for d.
I'll be using elimination in this case:
-2(2p + 3d = 18.25) --> -4p - 6d = -36.50
-4p - 6d = -36.50
4p + 2d = 27.50
-4d = -9.00
d = 2.25
4p + 2 * 2.25 = 27.50
4p + 4.50 = 27.50
4p = 23.00
p = 5.75
Now let's check our answer:
2 * 5.75 + 3 * 2.25 = 18.25
11.50 + 6.75 = 18.25
18.25 = 18.25
So drinks cost $2.25 and popcorn $5.75

I do not see any other zero other than that in the $50. I will still try to help. The zero in 50 denotes that 50 is a multiple of ten. I hope this helped.
