Question

4. Liam can work at most 20 hours a week but he needs to earn at least $125. His dog-walking job pays

Answer 1

Two possible solutions are: (4.5, 8.5) and (8, 6.3)

How to graph the inequality?

Let x represents hours dog walking and y represents hours washing cars.

So, we have:

Earnings = Rate of dog walk * x + Rate of car wash * y

This gives

Earnings = 7x + 11y

He wants to earn at least $125.

This means that:

7x + 11y ≥ 125

See attachment for the graph of the inequality

From the attached graph, two possible solutions are: (4.5, 8.5) and (8, 6.3)
