Suppose lisa starts driving for uber as a part-time job to supplement her income as a home-based web designer. when working as a web-designer she can make $25 per job and each day and can complete 2 additional jobs in the first hour of work but by the eighth hour she can only produce an additional 0.5 jobs. what hourly rate would lisa need driving for uber to induce her to drive for uber in that 8th hour instead of web designing?

$12.5(at least) would be needed to induce Lisa for driving Uber instead of working on web designing.

Explanation:

Lisa makes $25 per job on web designing from her home and in the first hour she can complete 2 additional jobs. But as per the question by the eight hour she can only do .5 jobs which means that for the eight hour she would earn -

                        .5 x $25 = $12.5 ( per job she gets $25)

So if Lisa goes on doing work as uber driver she is going to loose $12.5 in the eight hour , so we can say that if Lisa is offered $12.5 hourly rate to work as cab driver then she is not going to miss out on the money she would have made as web designer from home.

answer; whoever is willing and able to pay the price;
