F(x)·g(x) = (3x +4)·(5 -x) = -3x^2 +11x +20
(f·g)(x) = -3x^2 +11x +20
The answer is £316.80.
This is because you're working out the original price from a percentage increase.
To do this, you do the original price ÷ (1- percentage increase as a decimal).
So it would be 352 ÷ (1 - 0.10) which is 352 ÷ 0.9.
And that equals to £316.80.

Step-by-step explanation:
We can think of this as an equality
5 Lawns = 8 Hours
If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:
5 x (5) = 8 x (5)
Therefore she mows 25 Lawns in 40 Hours
