You're very selcome.
To find the 4th month's hourly rate in terms of the first month's hourly rate, we need to consider the cumulative increase over the three months.
Let's assume Jack's first month's hourly rate is x dollars.
In the second month, he earns an additional $0.05 on top of his first month's rate, so his second month's hourly rate is x + $0.05.
In the third month, he again earns an additional $0.05 on top of the second month's rate, so his third month's hourly rate is (x + $0.05) + $0.05 = x + $0.10.
Now, to find the 4th month's hourly rate, we add another $0.05 to the third month's rate: (x + $0.10) + $0.05 = x + $0.15.
Therefore, the 4th month's hourly rate in terms of the first month's rate is x + $0.15.
