Tim babysits for three hours on the weekend. His current babysitting job pays him $7 an hour. He has a new babysitting job offer that would pay him $10 an hour for two hours on the weekend. What would be the total costs or benefits to Tim's money and time if he took the new babysitting job?

The benefit to taking the new job is the higher pay rate and move time the cost is the money he would make at his old job by working 3 hours

Before going to the cost and benefits, lets take a look first at the total of what Tim makes for the two jobs. In the first job, he is paid $7 per hour for 3 hours so that is $21 total for the first job. The second job offer is $10 per hour for two hours so that is $20 for the entire second job offer. If he is going to take the first job, he will have $1 more than the second job, however, he has to work an extra hour. However, if he takes the second job, he receives $1 less but has one hour more for himself. So if he were to take the second job, it will be more beneficial to him because he can get almost the same amount but doesn't need to work as hard
