Question

Jacobs's job pays him $12.50 per hour. Which equation can be used to find Jacob's salary (y) if he works for x hours?

y = x / 12.50
y = 12.50x
y = 12.50 + ×
y = 12.50 - ×

Answer 1

The equation to calculate Jacob's salary (y) based on the number of hours he works (x) at his job that pays $12.50 per hour is given by y = 12.50 × x.

Step-by-step explanation:

To find Jacob's salary (y) for x hours of work, we need to create a linear equation that correlates his salary with the hours worked. Since Jacob is paid $12.50 per hour, we multiply the number of hours (x) by his hourly wage to calculate his total salary. Therefore, the equation to find Jacob's salary is y = 12.50 × x.

Example 12.4 with Svetlana and the Try It Σ with Ethan illustrate the setup of linear equations for wages. Unlike Svetlana's and Ethan's situations, which include a fixed fee plus an hourly rate, Jacob's salary does not have a fixed fee and is instead a straightforward multiple of hours worked by the hourly rate.
