The amount of a person’s paycheck p varies directly with the number of hours worked t. For 22 hours of work, the paycheck is $126.50. Write an equation for the relationship between hours of work and pay.

1 answer

Since the paycheck \( p \) varies directly with the number of hours worked \( t \), we can express this relationship mathematically as:

\[ p = kt \]

where \( k \) is the constant of variation.

To find \( k \), we can use the information given about the paycheck for 22 hours of work:

\[ 126.50 = k \cdot 22 \]

Solving for \( k \):

\[ k = \frac{126.50}{22} = 5.75 \]

Now that we have the value of \( k \), we can write the equation that relates the hours worked to the pay:

\[ p = 5.75t \]

This is the equation that describes the relationship between hours of work and pay.
