The remaining students do not win a prize. If 250 students play the game at the booth, how much money should the carnival committee expect to pay for prizes for that booth?

28% = 28/100 = 0.28;  14% = 14/100 = 0.14;  8% = 8/100 = 0.08 so:

money = 0.28*250*3.65 + 0.14*250*1.2 + 0.08*250*7.5

$${\mathtt{money}} = \left({\mathtt{0.28}}{\mathtt{\,\times\,}}{\mathtt{3.65}}{\mathtt{\,\small\textbf+\,}}{\mathtt{0.14}}{\mathtt{\,\times\,}}{\mathtt{1.2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{0.08}}{\mathtt{\,\times\,}}{\mathtt{7.5}}\right){\mathtt{\,\times\,}}{\mathtt{250}} \Rightarrow {\mathtt{money}} = {\mathtt{447.5}}$$

money = $447.50 .
