To rent a car Cesar must pay $15 a day plus 50 for every mile he drives. in dollars, what is his final bill if he rents a car for 3 days and drives a total of 50 miles?​

Step-by-step explanation:

1. 50x50 (because 1 mile= $50)=2500

2. 15x3 (because you need to pay 15 dollars a day)= 45

3. 2500+45= $2545

( plus tax that would be $2,875.85 IF YOUR IN CANADA )

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

the correct option is b
