Chapter SH, Problem 6.3.12EP

To determine

To calculate: The amount of gallons that the child consumes in one year.

Answer to Problem 6.3.12EP

The required amount of gallons of milk that the child consumes in one year is 109.5 gallons per year.

Explanation of Solution

Given information:

The rate of milk that the child consumes = 48 ounces per day

Calculation:

The given rate can be expressed in fraction as,

  $\frac{48\text{ounces}}{1\text{day}}$

It is known that 1 year = 365 days

And, 1 gallon = 160 ounces

To find amount of gallons of milk that the child consumes in one year, multiply the above fraction by $\frac{1\text{gallon}}{160\text{ounces}}$ and $\frac{365\text{days}}{1\text{year}}$ .

  $\begin{array}{c}\frac{48\cancel{\text{ounces}}}{1\cancel{\text{day}}}\times \frac{1\text{gallon}}{160\cancel{\text{ounces}}}\times \frac{365\cancel{\text{days}}}{1\text{year}}=\frac{48\times 365}{160}\text{gallons}/\text{year}\\ =\text{109}\text{.5}\text{gallons}/\text{year}\end{array}$

Hence, the required amount of gallons of milk that the child consumes in one year is 109.5 gallons per year.
