Answer:
The answer is -1.255 for residual value.
Step-by-step explanation:
We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:
Residual value = Observed value - predicted value
Residual value = 26 - 27.255
Residual values = -1.255
Answer: $144
Step-by-step explanation:
8 tiles = $192
1 tile = $24
2 tiles = $48
192 - 48 = 144
she returned 2
8 - 2 = 6
6 tiles = $144
By using the concept of profit, it can be calculated that
Profit function = 5.75 x - 1200
What is profit?
If the selling price of an article is more than the cost price of the article, the difference between the selling price and cost price gives the profit
Monthly expense for a pizza parlor C(x) = 1,200 + 6. 75x
Revenue function = 12.5x
Profit function = R(x) - C(x)
= 12.5x - (1200 + 6.75x)
= 12.5 x - 1200 - 6.75x
= 5.75 x - 1200
