Answer:
Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.
Step-by-step explanation:
In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x for the sale of x video games
As we know profit = sale price - cost price
Therefore P(x) = R(x) - C(x)
Or P(x) = (R-C)x = 60x - (12+7x)
P(x) = 60x -12 - 7x
P(x) = 53x -12
Now the profit on selling 20 video games will be
P(20) = 53×20 -12 = 1060 -12 = 1048.
The total number of people that all the cars can hold is greater than 480 and less than 500 people.
A: According to the given situation, where both the number of trolley cars and the number of people in each car must have two digits and be less than 30.
Hence, the possible number of trolley cars in the park = 22 and a possible number of people in each car= 22
B: explain how you found your answer.
Lets suppose the number of cars be =c and the number of persons be= p
As the number of cars and number of person are same, so c=p
so,
should lie the given range of 480 to 500.
Now, the nearest perfect square that lies between 480 and 500 is 484.
The square root of 484 is 22. So, the number of cars and people are 22.
C: This is the only hit and trial method for solving this question.
