Using a linear function, it is found that you would need roughly 24 hours of training to have a monthly pay of $1500.
What is a linear function?
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Looking at the table, the pay increases $200 each 10 hours of work, hence the slope is:
m = 200/10 = 20
Then:
y = 20x + b
When x = 10, y = 1220, hence:
y = 20x + b
1220 = 20(10) + b
b = 1020.
Then the pay for x hours of training is:
y = 20x + 1020.
For a pay of $1500, we have that:
y = 20x + 1020.
1500 = 20x + 1020.
20x = 480
x = 24
You would need roughly 24 hours of training to have a monthly pay of $1500.
