Hi everyone here we have a question telling us that a mole of quarters is distributed among Canada's population, Which is 36,991, people. And our goal here is to calculate the amount each person would receive. So one more equals all the God Rose number, Which is 6.02, 2 times 10 To the 23rd units. So we're gonna start out with avocados number 6. Times 10 : 23rd units. And then we're going to divide that amongst the people. So we're going to divide that by our 36 million 991,000 981 people. And that equals 1.627, nine times 10 to the 16th quarters per person. And now we need that amount in dollars. So we're going to use our 1. Times 10 to the 16th quarters per person. And we're going to multiply that by $ over four quarters and that equals 4.07 Times 10 to the 15th dollars per person. And that is our final answer. Thank you for watching. Bye.
