A certain school had a fund raising activity. Each board member was requested to sell two (2) tickets on the first day and double the sales each day for 10 days. If Mr. Santos, a board member, met his quota. How many tickets did he sell on the 10th day? If a ticket costs 50 each and a seller is given 5% commission of the total sales. How much will Mr. Santos receive for his commission?
By "doubling the sales." I'm assuming that you mean the previous day's sales......
We can find the total number of tickets sold with this sum
∑ 2n = 2046
n = 1
On the 10th day he would have sold 2^10 = 1024 tickets
His total sales = 2046 * .50 = $1023
Since he makes a commission of 5%, he receives $1023 * .05 = $51.15
