How much water must be added to 10 gallons of 10% brine solution to decrease the concentration to 3%? | [
"0—1.5 gal",
"16+ gal",
"1.5—3 gal",
"4.5—6 gal"
] | B | Let amount of water that must be added in gallons to dilute concentration of brine solution = x
Amount of brine already present = 10/100 * 10 = 1 gallon
1/(10+x) *100 = 3
=>100 = 30 + 3x
