At a booth at the school carnival in past years, they've found that 28% of students win a stuffed toy ($3.65), 14% of students win a jump rope ($1.20), and 8% of students win a t-shirt ($7.50). 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

 

money=(0.28×3.65+0.14×1.2+0.08×7.5)×250⇒money=447.5

 

money = $447.50
