A travel company uses a quadratic function to model the profit, in dollars, that it expects to earn from selling
tickets to a river cruise at d dollars per person. The
expression - d^2 + 100d – 900 defines this function.
Without graphing, find the price that would generate the
maximum profit. Then, determine that maximum profit.

hows it hangin lol

step-by-step explanation:

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.

hope this : )
