Question

Tra'von earns $9 an hour working after school at the supermarket. Write an expression for how much money he will earn for x hours of work.

Answer 1

The expression for how much money Tra'von will earn for x hours of work is given by the product of his hourly wage and the number of hours worked. The expression can be written as 9x, where x represents the number of hours worked, and $9 is Tra'von's hourly wage.

Step-by-step explanation:

In this scenario, Tra'von earns $9 per hour, and the variable x represents the number of hours he works. To find the total earnings, you multiply the hourly wage by the number of hours worked. The expression 9x encapsulates this relationship, providing a straightforward way to calculate Tra'von's total earnings for any given number of hours worked.

For example, if Tra'von works 5 hours, substituting
`\( x = 5 \)` into the expression
`\( 9x \) gives \( 9 * 5 = 45 \).` Therefore, Tra'von would earn $45 for 5 hours of work.

This expression is an algebraic representation that simplifies the process of determining earnings based on the number of hours worked, making it a versatile tool for calculating Tra'von's total income in various work scenarios.
