The Buck Creek fire department served 250 dinners. A child's plate cost $5.50 and an adult's plate cost $9.00. A total of 1935 was collected. How many of each type of plate was served. Answer by sachi(548) (Show Source):
You can put this solution on YOUR website! let there are x children so no of adults=250-x
as per question
x*5.5+(250-x)*9=1935
or 5.5x+2250-9x=1935
or -3.5x=1935-2250=-315
or x=315*3.5=90
so there are 90 children so no of adults=160
