A computer technician keeps track of his earnings throughout each month. the technician observes that his earnings are a linear function of the number of hours he works during the month. The technician finds that when he works 55 hours during the month, he earn $2,125 and when he works 30 hours, he earns $585
Part A: Write a linear function to model the relationship between the number of hours worked and the money earned.
Part B: Explain the meaning of slope in the context of the problem.
by working 25 extra hours, he earned $1540 more. That's $61.60/hr
So, his pay for x sours is
p(x) = 61.6x-1263
the slope is the rate of change ($ per hour), or his hourly rate.
Where did you get 1263 from>?
yea whered you get 1263 from?
Plug the slope of 61.6, y of 585 and an x of 30 to get the y-intercept of -1263 which is b. So your formula would be y = 61.6x - 1263 for this problem.
