A concession stand sells either hotdogs for $1.75 each or hamburgers for $4 each. If Charlie buys a total of 9 items from the concession stand for a total of 27 dollars, then how many hotdogs did he buy?
(A) 3
(B) 4
(C) 6
(D) 7
(E) 8
Kudos for correct solution.
Let x = hotdog and y= hamburg
therefore we have x+y = 9 (since he buys 9 items)
and 1.75x +4y = 27 (total cost of hotdog and hamburg)
Solving for x we get
x=4
Can you plz mention the source
