Answer 1

The rate per hour when working for 150 hours is $13.33.

The rate per hour when working 50 hours less is $20.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount to be earned = $2000

The number of hours to work = 150 hours.

The rate per hour to earn $2000 in 150 hours.

= 2000 / 150

= $13.33

Now,

The number of hours is reduced to 100 hours.

The rate per hour to earn $2000.

= 2000 / 100

= $20

Thus,

The rate per hour when working for 150 hours is $13.33.

The rate per hour when working 50 hours less is $20.
