Answer:
c = 15n + 50
Step-by-step explanation:
the total cost = $15 for each person ( n ) + a $50 flat fee
Area= length*width
width=W
W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)

Answer:
Online Ordering is better.
Step-by-step explanation:
So you now that you save 20% if you to physical store and you save $20 if you go to the online store.
Say you are spending 100 dollars at the store to make it easy. 20% of one hundred is $20 so that is the same amount of money.
Now let’s look at the taxes and shipping so at the physical store you have to pay taxes no matter what but online you only do it if you purchase is less than $75 and we have $80 ($100–$20=$80) so at the physical store you have some amount of Mandy that is more than $80 because of taxes but if you buy online it will be exactly $80.
Combine the terms. Note that: one positive and one negative sign results in a negative sign.
Simplify: 5 + (-4) = 5 - 4 = 1
1 + (-7) = 1 - 7 = -6
-6 + 2 = -4
-4 is your answer
