## anonymous 5 years ago you have a part time job at a local restraunt. One evening you work 3 hours and earn 20.25. on Saturday you work 6 hours and earn 40.50. determine your hourly wage, the rate of the change.

Is this a calc problem? it mentions "rate of change" which is a derivative in calculus

2. anonymous

rate of change just means compute the slope of $(3,20.25), (6,40.5)$

although, i would just say, if it's a simple problem, make it (amount earned)/(number of hours worked)

so you get dollars per hour which is still a rate of change

5. anonymous

a really dumb question since unless you get paid for just showing up you might as well divide $\frac{20.25}{3}$

6.75 dollars/hour

7. anonymous

no reason to compute a slope for sure. unless you get money for clocking in. you make \$6.75 per hour

as long as you have something/something, it's a rate of change

20.25 ------- ; it the second data point wasnt a scalar of the first then wed have to 3 do a little more work to find the average hourly pay

if I work for 3 hours and make 20.25; then I expect to work for 6 hours at the same pay scale and make 40.50 since I worked twice as long

12. amistre64

we can put in a 0 pay for 0 hours work and see if it matches up to a line or a quad :)

13. amistre64

pay = 6.75h

14. anonymous

this is a dumb question yes

15. amistre64

(6,40.50) (3,20.25) --------- (3,20.25); slope = y/x = 20.25/3 = 6.75

wage = pay / time worked. they gave us

17. amistre64

not really 'dumb'. Its a simple question yes; but not a 'dumb' question perse..

sorry guys, im not a math person....
