​These inequalities describe the conditions Leah needs to meet to earn at least $120 per month while not exceeding a total of 20 hours of work.

Let's set up an equation to represent Leah's earnings based on the given information.

Leah earns $5 per hour babysitting, so the earnings from babysitting (in dollars) would be 5x.

She also earns $8 per hour working at the ice cream shop, so the earnings from the ice cream shop (in dollars) would be 8y.

Leah's total monthly earnings must be at least $120, so we can write the inequality:

5x+8y≥120

Leah cannot work more than a total of 20 hours per month, so the total number of hours worked (x+y) must be less than or equal to 20:

x+y≤20

So, the system of inequalities to represent Leah's situation is:

5x+8y≥120

x+y≤20

​These inequalities describe the conditions Leah needs to meet to earn at least $120 per month while not exceeding a total of 20 hours of work.
