Answer 3.

$\bf \:Small \: bottle \: hold \: 25 \: ounces \: of \: water$

$\bf \:Large \: bottle \: hold \: 55 \: ounces \: of \: water$

Answer 4.

• The Institute of Medicine (IOM) recommends that men drink at least 101 ounces of water per day, and women should drink at least 74 ounces.

So, it means she drank enough water.

Step by step explanation:-

Let amount of water in small bottle be 'x' ounces and amount of water in large bottle be 'y' ounces.

Case :- 1.

Melba drank 5 small bottles of water and 1 large bottle for a total of 180 ounces.

$\bf\implies \:5x + y = 180.....(1)$

Case :- 2.

Melba drank 4 small bottles of water and 1 large bottle for a total of 155 ounces.

$\bf\implies \:4x + y = 155.......(2)$

Subtracting equation (2) from equation (1), we get

$\bf \:5x + y - (4x + y) = 180 - 155$

$\bf\implies \:5x + y - 4x - y = 25$

$\bf\implies \:x = 25$

Put x = 25, in equation (2) we get

$\bf\implies \:4 \times 25 + y = 155$

$\bf\implies \:100 + y = 155$

$\bf\implies \:y = 55$

So, it means Small bottle hold 25 ounces of water and Large bottle hold 55 ounces of water.
