Last year your job at the university cafeteria paid you $9 an hour and the price of a ten-minute long distance call to your girlfriend in California was $4. This year your cafeteria job pays $9.90 per hour and the ten-minute phone call now costs $4.10. You are clearly:

Better off because the phone call now costs less work

Explanation:

It should be noted that during last year, he was paid $9 per hour for the job he was doing with University cafeteria, and a ten minute call to his girlfriend cost $4, but this year, the pay for the same rate of work has increased to $9.90 while the price of a-ten - minute call also increased to$4.10.

This clearly shows that, this person is better off this year compared to last year. This is because, the money, he will be spending on the call is lesser to last year compared to the money he is being paid for the work he is doing this year.

This means that, after he had paid for the ten minutes call, he will still have more than what he used to have when he made the same quantity of the call last year.

You're clearly doing better than last year because your income increased and the increase in the phone call with respect to your increased income is not as much as the previous year own.
