So, for each value in the "Tickets sold" column, you would multiply by 2 to find the corresponding value in the "Dollars donated" column. For example:
If 10 tickets are sold, the amount donated would be 10 * 2 = $20
If 20 tickets are sold, the amount donated would be 20 * 2 = $40
If 30 tickets are sold, the amount donated would be 30 * 2 = $60
If 40 tickets are sold, the amount donated would be 40 * 2 = $80
If 50 tickets are sold, the amount donated would be 50 * 2 = $100
