Answer:
Yes, she is correct. If she did 100% of the work time, it would be 15 hours, so instead of multiplying by 1, we multiply by 1.2. 15 times 1.2 is infact 18. So she is justified in saying that she spent 120% more time this week.

Answer:
2x-3
Step-by-step explanation:
f(x) = 3x-1
g(x) = x+2
Find (f-g)(x), this means we need to subtract g from x.
(3x-1) - (x+2)
Subtract the like terms:
3x -x = 2x
-1 -2 = -3
Combine them to get 2x-3
