Answer :
Final answer:
The woman worked 20 hours on the second job.
Explanation:
To solve the problem of determining the number of hours the woman worked on the second job, we can set up a system of equations based on the given information:
She earns $35 per hour on the first job.
She earns $25 per hour on the second job.
The total earnings for the week is $1330.
She works twice as many hours on the first job than the second job.
Let's denote the number of hours worked on the second job as x. Then the hours worked on the first job would be 2x. Let's assume that the woman worked x hours on the second job.
According to the given information, she worked twice as many hours on the first job, which means she worked 2x hours on the first job.
Her earnings from the first job would then be $35 * 2x, and her earnings from the second job would be $25 * x.
As per the question, her total earnings for the week were $1330.
So, we can write the equation:
$35 * 2x + $25 * x = $1330
Solving this equation, we find that x = 20.
Therefore, the woman worked 20 hours on the second job (option c).
