Hope this helps
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
