Step-by-step explanation:
<em>The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.</em>

From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:
![Total = 3p](https://tex.z-dn.net/?f=Total%20%3D%203p)
Now assume that p is 10 square feet (from part A).
The total will be:
![Total = 3*10](https://tex.z-dn.net/?f=Total%20%3D%203%2A10)
![Total = \$30](https://tex.z-dn.net/?f=Total%20%3D%20%5C%2430)
Answer: 7.50x500...try that and that’s your answer
Step-by-step explanation:
Answer: 6700 meters
Step-by-step explanation:
From the question given, we are informed that Gephart is traveling from his house to the history museum and that the distance from home to the history museum is six and seven-tenths kilometers.
In order to know the distance in meters
that he will travel to the museum, we have to multiply the convert the distance given in kilometers to meters. This will be:
1000 meters = 1 kilometer
Therefore, 6 7/10km = (6 7/10 × 1000m)
= 6 7/10 × 1000
= 67/10 × 1000
= 67 × 100
= 6700 meters
He'll travel 6700 meters to the museum.
For this case we have the following functions:
![f (x) = x ^ 2 + 5\\g (x) = 2x ^ 3-1](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20x%20%5E%202%20%2B%205%5C%5Cg%20%28x%29%20%3D%202x%20%5E%203-1)
By definition of composition of functions we have:
![(f / g) (x) = \frac {f (x)} {g (x)}](https://tex.z-dn.net/?f=%28f%20%2F%20g%29%20%28x%29%20%3D%20%5Cfrac%20%7Bf%20%28x%29%7D%20%7Bg%20%28x%29%7D)
Then substituting:
![f (-3) = (- 3) ^ 2 + 5 = 9 + 5 = 14\\g (-3) = 2 (-3) ^ 3-1 = 2 (-27) -1 = -54-1 = -55](https://tex.z-dn.net/?f=f%20%28-3%29%20%3D%20%28-%203%29%20%5E%202%20%2B%205%20%3D%209%20%2B%205%20%3D%2014%5C%5Cg%20%28-3%29%20%3D%202%20%28-3%29%20%5E%203-1%20%3D%202%20%28-27%29%20-1%20%3D%20-54-1%20%3D%20-55)
So:
![(f / g) (- 3) = \frac {14} {- 55} = - 0.25](https://tex.z-dn.net/?f=%28f%20%2F%20g%29%20%28-%203%29%20%3D%20%5Cfrac%20%7B14%7D%20%7B-%2055%7D%20%3D%20-%200.25)
Answer:
![(f / g) (- 3) = \frac {14} {- 55} = - 0.25](https://tex.z-dn.net/?f=%28f%20%2F%20g%29%20%28-%203%29%20%3D%20%5Cfrac%20%7B14%7D%20%7B-%2055%7D%20%3D%20-%200.25)
