Cam's math-a-thon fundraiser

My wonderful math nerd, Cameron, is taking part in a math-a-thon over the next 3 weeks to fundraise for school. His aim is to get to 9000 points & he is looking for sponsorship. He is after a few awesome people to sponsor him an amount for every 1000 points earned...it's estimated that it'd take 45mins to get 1000 points. Example: sponsor $1 per 1000 points = $9 sponsorship if he reaches goal... also you can add a bonus if his goal is achieved! He is quite keen on this as a fundraiser as it's totally more his thing than the silly fun runs that the school normally does!! 😁 ➕✖➖➗ 😁
