Celine has a bottle that contains 20% of milk and the rest water. The bottle has 1 liter of water. Part A: Write an equation in
one variable that can be used to find the total number of liters of milk and water in the bottle. Define the variable used in the equation. (5 points) Part B: How many liters of milk are present in the bottle? Show your work. (5 points)
A. a=all 0.20a+1=a minus 0.20a both sides 1=0.80a divide both sides by 0.80 1.25=all all-water=milk 1.25-1=milk=0.25 there is 0.25 liters of milk in the bottle
B)The rate of change is constant because for every 5 seconds the change is the same. For every 5 seconds, the height decreases by 60ft. The equation is y=12x+1210
