Given :
A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.
The same meal cost $15 a person with no fee at Good Eats.
To Find :
When does we cater become the better deal.
Solution :
Let , x is number of order .
Cost at cater , C = 12.5x + 30 .
Cost at Good Eats , G = 15x .
We need to find :
G > C

Therefore, after 12th order cater will be more value for money.
Hence, this is the required solution.
Answer:
x= 5e
Step-by-step explanation:
because e is in parantaces
Answer:
I think it is B I am sorry if wrong
Assuming ya mean

take derivitive
remember dy/dx e^x=e^x
also the chain rule
so

find where it equals 0


multiply both sides by e^x

divide both sides by 8

take ln of both sides


divide both sides by 9

x≈-1/5
f'(-1)<0
f'(0)>0
so it is increasing from x to infinity
the interval it is increasing on is
