Question

Nick works two jobs to pay for college. He tutors for $15 per hour and also works as a bag boy for $8 per hour. Due to his class and study schedule, Nick is only able to work up to 20 hours per week, but must earn at least $150 per week. If t represents the number of hours Nick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario?
t + b >= 20
15t + 8b = 150
t + b <= 20
15t + 8b >= 150
t + b <= 20
15t + 8b <= 150
None of the systems shown represent this scenario.

Answer 1

@ZeHanz can u help with this one too ?

Answer 2

i have this and two others left

Answer 3

OK, I will give it a try!

t is the number of tutor hours,
b is the number of bag hours.

The total number of hours worked is t+b, can be no more than 20
His earnings with these activities will be 15t+8b, must at least be 150.

Could you translate this to the right inequalities now?

Answer 4

not into the exact inequalities but i think i would be dealt with t + b <= 20
15t + 8b >= 150 either that or none of the systems shown

Answer 5

Looks OK to me!

Answer 6

so which one then ? @ZeHanz

Answer 7

You chose option B yourself, so I didn't think you needed more help.
So, It's B, it's B, it's B! (you may sing it)

Answer 8

lol thanks i was sure if it was b or d

Answer 9

The graph below is represented by which system of inequalities?



-x + 3y < 9
y > -2x + 1

-x + 3y <= 9
y > -2x + 1

-x + 3y < 9
y -2x + 1

None of these systems represent the graph shown.

Answer 10

Have a little confidence in your reasoning. You are doing fine!
