The number of hours to reach the total for the first year is 48.4 hours
The missing information in the question are:
Total for the first year = $266
Table of values
x y
10 55
20 110
30 165
40 220
Let x represent the number of hours and y represent the total earning in x hours.
The hourly rate is given as:
Rate = $5.5
This means that:
y = 5.5x
In (a), we have
y = 5.5x
Substitute 266 for y
5.5x = 266
Divide both sides by 5.5
x = 48.4
Hence, the number of hours to reach the total for the first year is 48.4 hours
