During the Christmas holidays, all shops are closed for 3 days. During each day during this time, a shop called "Surprise" could have earned 5 thousand dollars. How much potential revenue did the "Surprise" shop lose during 6 years of activity?
In one day the shop is losing 5 thousand dollars, so during three days, the losses are 5 * 3 = $15,000.
Christmas holidays are once a year, so in 6 years the shop "Surprise" could have earned another $15,000 * 6 = $<<6*15000=90000>>90,000.
