Actually, you would only get 15 robux if you clicked that because there is a decimal point, and decimal points don't add place value, they only add digits. There would have to be a comma, not a decimal point. This is 100% a scam, unless you only want 500 robux. However, there is the question of why they would be giving out 15 robux anyway. As well as why they would be giving out 500 robux. Also, you can't give out 2.5 robux. (By simplifying, you get 2.5 out of 2.500)
