Could you please help me on this. Thank you

Please detail all the calculations. Thank you Some cars (about half) have oxidized paint (no shine) at the time wax is to be applied, requiring cleaning with an oxidation cleaner before one can apply regular car wax. Oxidation cleaner costs $2.50 per bottle (good for one application) and can be applied in about the same time required to apply either an oxidation cleaner or regular wax, about two hours. An additional advantage of Miracle Shield, however, is that it both removes the oxidation and shines the car's surface in one step. Consequently, Miracle Shield can be applied directly to a car's surface that is already highly oxidized. Question: Making any reasonable assumptions that you need to make - be sure to state your assumptions, estimate the economic value of Miracle Shield. (You may assume that Miracle Shield is the only alternative to car wax available in this market. You may assume a labor cost of a person's leisure time who waxes his/her own car. Ignore the time value of money.) Example: Time=1 year, how many applications would you do in a year = how much you would 'spend' on time & supplies to complete this task; then calculate for the other method/product
