Explanation:
To determine the number of hours Sarah would have to work for each job to earn $1000, we need to set up an equation based on the given information.
Let’s assume Sarah works x hours for the first job and y hours for the second job.
The amount earned from the first job would be dollars, and the amount earned from the second job would be 13y dollars.
According to the given information, the total amount earned should be $1000. Therefore, we can write the equation:
15x + 13y = 1000
To find the values of x and y, we need additional information or constraints.
