You earn $6 per hour babysitting and $10 per hour working at a gas station. You want to earn at least $90 to cover your weekly

expenses and have at most 15 hours available to work this week. The gas station requires you to work at least six hours per week.

Write a system of linear inequalities to model this situation.

OF B + G > 90

6B + 10G< 15

G> 6

O G 6B + 10G > 90

B + G > 15

G<6

OH 6B + 10G > 90

B + G < 15

G 26

Answer:

[tex]B + G \leq 15[/tex]

[tex]6B + 10G \geq 90[/tex]

Step-by-step explanation:

Given

Represent Babysitting with B

Represent Gas Station with G

Total workhours = At most 15

Earnings = At least $90

First, we need to represent the work hours as inequality

B + G = At most 15

At most 15 means less than or equal to 15.

So, we have:

[tex]B + G \leq 15[/tex]

Next, we represent the earnings as inequality.

6 hours of babysitting is: 6B

10 hours at gas station is: 10G

So:

6B + 10G is at least 90

At least 90 means greater than or equal to 90

So, we have:

[tex]6B + 10G \geq 90[/tex]
