Just put down no solution. It's unsolvable.
Given ,
Concentrate= 250 mL
Water = 1 liter = 1000 mL
A) ratio is 250:1000 = 1:4
B) for 250 mL it is 1 liter now for 2000mL it is X .
=> x = 2000/250 = 8 liters
C) volume of water in 6L of made up juice is 1500 mL
D) 1 liter - 5 glasses
For 80 glasses it would be 80/5 = 16 glasses
i believe the answer would than have to be 17,24,31,45,52
Try using a calculator i don't have one on me sorry :(
