Answer:

y = 25x + 128.8

Step-by-step explanation:

y = total cost

x = amount of days the car was rented

25 represents the daily charge for the fee and the insurance (15+10=25)

128.8 represent the cost for miles driven by Jerry

This was calculated by multiplying the amount of miles he drove (644) by the cost of each mile (.20)

644x.20=128.8 so the cost for miles driven is $128.8 which is why it was added to the equation

The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?

Answers

Answer:

625

Step-by-step explanation:

Let two number be x and (50-x).

The product of numbers be x(50-x).

P = 50x-x²

For maximizing the product,

[tex]\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25[/tex]

So, the maximum product, P = 50(25)-(25)²

P = 625

Hence, the maximum value of the product of these two numbers is 625.

Combine like terms: 5x + 5x = 10x

10x = 10x

Add '-10x' to each side of the equation.

10x + -10x = 10x + -10x

Combine like terms: 10x + -10x = 0

0 = 10x + -10x

Combine like terms: 10x + -10x = 0

0 = 0
