The function is graphed as shown below
Part A:
We use the formula
to find the vertex of the function. A quadratic function of the form of
and equating this form to the given function
, we have
and
.
Substituting
and
into the vertex formula, we have
, as shown in the graph
This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos
Part B:
We can find solution to this equation by factorising
and
, as shown in the graph
The two values means that the company makes no profit when they either produce 5 or 15 photos

Step-by-step explanation:
Answer:
24 miles
Step-by-step explanation:
In order to calculate Judy's estimation, we would simply have to multiply the actual distance in kilometers of the tour by the number of miles that Judy believes are in a single mile. This would give us Judy's estimation for how long the tour would be in miles.
40 km. * 0.6 miles = 24 miles
Finally, we can see that Judy's estimation would be that the tour is 24 miles long. Using Judy's believed conversion rate.
Answer:
This would mean that the next year her car's value would go down by $2,625. The new value of the car would consequently be $34,875.
<h3><u>
Step-by-step explanation:</u></h3>
<em>Here is how you can solve this problem:</em>
- Okay, so first, let's find 7% of $37,500. To do this, the simple way would be to find first 1% of $37,500.
- 1% of $37,500 is $375. This is because you are moving the decimal point two spaces to the left.
Now that we know that 1% of $37,500 is $375, let's multiply this value by 7.
- Subtract 2625 from 37,500.
Let's say that the next year, her car value goes down by 7% again.
THIS IS THE IMPORTANT PART:
<em>YOU FIND 7% OF THE NEW VALUE, NOT $37,500. YOU WOULD FIND 7% OF $34,875.</em>
<em>Hope this helps! :) </em>
