How many pencils do the three students want? ** The three students want a total of 3+2+5 = <<3+2+5=10>>10 pencils
How much do the three students want in total? ** Each pencil cost 20 cents so 10 pencils cost 20*10 = <<20*10=200>>200 cents
How much do the three students want in total? ** 100 cents make a dollar so 200 cents make 200/100 = <<200/100=2>>2 dollars
