The price is still the same, but Kennedy's money is still $2 less (because the money for the four-week trial is on him). In the United States, many sales experts convince customers in this way: how much money you will save every day, how much money you will save every year, how much money you will save in ten years, and some people even tear money while explaining it (Jin Kela).

1900 washing machine company's pricing is: 14 USD, of which $2 is paid in advance and 12 USD is paid in six weeks.

Kennedy's calculation is as follows: If you wash clothes once a week, you have to pay the laundryman $65,438 +0.2 (if you do it yourself, of course, the price is the same), then you have to spend $24 * 65,438+0.2 = $28.8 for this in 24 weeks (free trial for the first four weeks). And if you buy his washing machine, the total price is 14 dollars, then you will save $28.8-14 = 24.8 dollars in 24 weeks, that is, you will save $24.8 /24=0.62 dollars per week, which is roughly 60 cents, and 50 cents of the 60 cents saved will be distributed to the company every week.
