Mandarinka [93]
The answer is f(x) = 75, g(x) = 5x, h(x) = 5x + 75

Let x be the number of lessons.

The <u>flat rate of $75</u> as function f(x) can be expressed as: f(x) = <u>75</u>
<u>$5.00 per lesson x</u> as function g(x) can be expressed as: g(x) = <u>5x
</u>
The combination of two functions (f(x) and g(x)) is the amount the parent should pay:
h(x) = g(x) + f(x)
h(x) = 5x + 75

so.. when the quantity is \bf -\cfrac{{{ b}}}{2{{ a}}} , is when the profit \bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}  is the highest

after that, as you can see from the graph, it goes back down
