Question 927207: The manager of a fish store has water that is 10% salt and water that is 25% salt. He needs to fill an aquarium with 5 gallons of water that is 20% salt.
A.) write a system of linear equations that you can use to determine how many gallons of each type of salt water the manager should combine. Be sure to define your variables.
B.) solve the system and determine how many gallons of eah type of salt water the manager should combine. Show all your work Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = amount of 10% salt water
y = amount of 25% salt water
---
x + y = 5
10x + 25y = 20*5
---
put the system of linear equations into standard form
---
x + y = 5
10x + 25y = 100
---
copy and paste the above standard form linear equations in to this solver:

answer:
x = amount of 10% salt water = 1.666666 gal
y = amount of 25% salt water = 3.333333 gal
