Question 999199: You have 2 part time jobs working at a grocery store and at a clothing store. you earn $7.65 per hour at the grocery store and $8.50 per hour at the clothing store for the week , you earn $229.50.
1) write an equation in standard form that models your earnings. my answer is 7.65X + 8.50Y =229.50
2) write an equation in slop-intercept form that medels your earnings.
3) graph the equations that model your earnings. which equation did you use to sketch your graph? Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Your answer to #1 is good. You used X for hours at the grocery store and Y for hours at
the clothing store.
#2, slope-intercept form to model the earnings?
You already have earning modeled using two unknown variables X and Y and that was done
in standard form. Earning is based on two variable terms and this is done properly using
standard form. Slope intercept form would only isolate one variable for hours or the other.
You can either solve for X as a function of Y; or solve for Y as a function of X.
#3, again you could model earnings as a function of X and Y hours. X and Y remain as unknowns.
You can start with
This will give number of grocery HOURS on the x-axis and corresponding number of clothing store HOURS
on the y-axis. The fact MUST be specified this is for earning of $229.5 in a week, and at the specified
wage rates.
