judging from the question, I would assume that his fees are y=200+50x
I will assume that y=fee and x=number of hours (or units of time)
so
a. difference between 55 and 50, that is 5 so #2's fee is 5$ more for every hour he works
b. difference between200 and 150 means that contractor 1 gets 50 more initally than contractor 2

45 = 15% × n
15% =
45 = 0.15n
0.15 and 0.15 cancels out
300 = n
15% of 300 is 45
45 is 155 of 300
15% × x = 45
x = 45 ÷ 15%
x = 45 ÷ 15/100
x = 45 × 100/15
x = 4500/15
x = 300
Check:
15% × 300
= 15/100 × 300
= 15 × 3
= 45
45 is 15% of 300.
