Answer 2

Answer:

Step-by-step explanation:

1. Equations

X = 1 Small  Bottle water

Y = 1 Large Bottle water

Days 1 ---4X+1Y= 155 Ounces

Days 2 ---5X+1Y= 180 Ounces

5X + Y= 180 Ounces

4X + Y = 155 Ounces

-     -        -

--------------------------------

X + 0 = 25 Ounces

X =  25 Ounces

Put the Value of Y in Equation of Day 1

4 X +Y = 150 Ounces

4x25 Ounces + Y = 150  Ounces

100 Ounces + Y = 150 Ounces

Y =150 Ounces -100 Ounces = 50 Ounces

Small Bottle Contains 25 Ounces water

Large Bottle contains 50 Ounces water
