Answer:

The revenue function

R(x) =  - 2x² +490x +2500

Step-by-step explanation:

<u><em>Explanation:-</em></u>

The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x

The price p in dollars that the company can charge for the product is given by p(x) = x + 5

Revenue = price × demand

Revenue = p(x) × d(x)

Revenue = (x+5) ×(500-2x)

Revenue = x(500-2x)+5(500-2x)

Revenue = 500x - 2x² + 2500- 10x

Revenue =  - 2x² +490x +2500

Hatshy [7]

Answer:

$119.32

Step-by-step explanation:

Leiff decides to buy his video game, with a price tag of $128, at this site

he will get the 15% discount when he checks out.

100-15= 85%

Discounted price=85% of 128 is 0.85 \cdot 128=108.8

Leiff pays 5.3% sales tax on the discounted price

5.3% is 0.053

sales tax amount=0.053 times 108.8=5.7664

So we add the sales tax amount and shipping fee

108.8+5.7664+4.75=119.32

So $119.32 is the total amount

djverab [1.8K]

Given :

Ruth wants to buy a skateboard for $44.

She has $100 in her account. She spent $11.36 to buy stationary.

She also wants to buy some comic books for $3.72 each.

To Find :

The maximum number of comic books, n, that Ruth can buy so that she has enough money left to buy the skateboard.

Solution :

Money left after buying skateboard and stationary is :

Money left = $(100 - 11.36 - 44)

Money left = $44.64

Number of comic she can buy is :

n = \dfrac{44.64}{3.72}\\\\n = 12

Therefore, she can buy a maximum of 12 books.

Hence, this is the required solution.
