G A car rental agency rents 180 cars per day at a rate of 30 dollars per day. For each 1 dollar increase in the daily rate, 5 fewer cars are rented. At what rate should the cars be rented to produce the maximum income, and what is the maximum income

$33 per day

$5,445

Step-by-step explanation:

(30+x)(180-5x) = Income

Income = -5x² + 180x - 150x + 5400

I = -5x² + 30x + 5400

dI/dx = -10x + 30 = 0

x = 3

Rate: 30+3 = 33

Income = 33(180 - (5×3)) = 5445

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
