Respuesta :

The system of inequalities are 10x + 22y ≥ 110 and x + y ≥ 8 and values of x and y are 5.5 and 2.5 respectively.

What is inequality?

In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Total amount by washing cars = 10x

Total amount by tutoring = 22y

Total hours should be no less than 8

So,

x + y ≥ 8

And,

Total amount ≥ 10

10x + 22y ≥ 10

By substitution,

10(8 - y) + 22y ≥ 10

y ≥ 2.5

And x ≥ 5.5

Hence "The system of inequalities is 10x + 22y ≥ 110 and x + y ≥ 8 and values of x and y are 5.5 and 2.5 respectively".
