Answer: £83.70
Step-by-step explanation:
We can set up a ratio.
Let x be the amount he earns for 9 hours of work.

We can cross multiply:
x = 9*9.3
x = £83.70
To find (f+g)(x), add the equations and simplify by combining like terms.
(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5
Final answer: C
Remember that (x/2) is the same as (1/2)x. They both represent half of x.
X-3+2 is the answer to this question
