Question

A pizza delivery driver earns $5 an hour and works x hours per day. He also spends $9 a day on gas. Write an expression for how much the driver earns in one day.

Answer 1

The expression for how much the pizza delivery driver earns per day is 5x - 9, where x is the number of hours worked per day.

Step-by-step explanation:

The student asked to write an expression for how much a pizza delivery driver earns in one day, given the driver earns $5 an hour and works x hours per day, while also spending $9 a day on gas.

To calculate the driver's daily earnings, we can set up the following expression:

• Hourly earnings: $5 multiplied by x hours, which gives us 5x dollars.
• Daily gas expense: $9 which is subtracted from the earnings.

Therefore, the expression for the driver's daily net earnings is 5x - 9.
