Company X provides bottled water to its employees in 1 liter bottles, $2 each. At least how many 1L bottles must Company X buy monthly, so that new contract with $50 fixed monthly rate and $1 for 10L bottle each paid off? (Assume that no other costs apply)	Options
A) 28
B) 29
C) 30
D) 31
E) 27
let the no. of 1 liter bottles be x, so the no. of 10l bottles will be x/10 (to equate the vol.) since the total cost will be equal , 2x= 50+x/10 so x= 26.31 or 27. Answer is (27).
