Answer:

156.25

Step-by-step explanation:

f(x)=4(2.5)^{x-1}\\\\f(5)=4(2.5)^{5-1}\\\\f(5)=4(2.5)^4\\\\f(5)=4(39.0625)\\\\f(5)=156.25

Therefore, the 5th term of the geometric sequence is 156.25

The cost C (in dollars) for the care and maintenance of a horse and carriage is C=15x+2000 where x is the number of rides.
MissTica

Answer: 100 rides are needed to break even.


Step-by-step explanation:

We have given the cost function

C(x)=15x+2000 where x is the number of rides.

And rides cost 35$

⇒ revenue function would be 35 times x

i.e.R(x)=35 x , where x is the number of rides.

Break even point of a firm occurs when at a certain point x the total cost equals to the total revenue.

i.e. at break even point

total revenue=total cost

⇒35x=15x+2000

⇒35-15x=2000[subtract 15x from both sides]

⇒20x=2000 [simplify]

⇒x=2000/20[dividing both sides with 20]

⇒x=100

∴ 100  rides are needed to break even.
