Question

1. the table below shows the cost, in dollars, for different numbers of gallons of milk. cost of milk

number of gallons	3	5	6	9
cost (dollars)	11.67	19.45	23.34	35.01

what is the cost, per gallon, of the milk?

Explanation:

Step1: Select a row from the table

Let's take the first row where number of gallons is 3 and cost is 11.67 dollars.

Step2: Calculate cost per gallon

Cost per gallon = $\frac{Cost}{Number\ of\ gallons}=\frac{11.67}{3}$
$11.67\div3 = 3.89$

We can check with other rows. For example, with the second row: $\frac{19.45}{5}=3.89$, with the third row: $\frac{23.34}{6}=3.89$ and with the fourth row: $\frac{35.01}{9}=3.89$

Answer:

$3.89$
