Answer:

Valid solution:   (35,5)

Time constraint:  x+y≤40

Earning constraint:  25x+15y≥900

Step-by-step explanation:

x denote the number of hours Chris spends tutoring.

and y denotes the number of hours he spend referring.

It is given that:

  • Chris can work a maximum of 40 hours per week.

so, the inequality that can be formed using this information is:

                x+y≤40.

( Since he can't work more than 40 hours per week )

Similarly,

  • His tutoring job pays $25 per hour and he also makes $15 per hour refereeing soccer matches.

He needs to make atleast $ 900 in order to cover his expenses.

So, the inequality is:

                25x+15y≥900

Hence , we plot the graph of these system of inequalities to find the solution.

We see that the point:

(35,5) lies on the boundary line and hence it is a valid solution to the system of inequalities.

whereas the point (32,9) lies out of the feasible region and hence is not a valid solution.

Kelly needs to order lunch for orders 6 people at a business meeting. Her menu choices are chicken salad for a cost of $5 per pe
nirvana33 [79]
Ok , with that information we can write the equations
x + y = 6
5x + 4y = 28

Where x = how many people ordered chicken
and y = how many people ordered egg salad

Through elimination , we can set one of the variables in both equations equal so we can eliminate it :

(4)x + (4)y = (4)6
5x + 4y = 28

4x + 4y = 24. equation 1
5x + 4y = 28. equation 2

Now we can subtract the second equation by the first equation and isolate one variable:
equation 2 - equation 1

5x - 4x + 4y - 4y = 28 - 24

x = 4

Now that we discovered our x value ( How many people ordered chicken salad ) , we can apply it to one of the equations and discover y ( how many people ordered egg salad)

x + y = 6
x= 4
4 + y = 6

We can shift 4 to the other side of the equation by subtracting 4 from both sides of the equation:
4 - 4 + y = 6 - 4
y = 2

x=4 and y=2

So the awnser is :
4 people ordered chicken salad and 2 people ordered egg salad!

I hope you understood my brief explanation!!
