Question

The bar graph shows changes in price of regular gasoline each year from 1996-2010. For example, at the end of 1996, the price per gallon for regular gasoline was $0.15 more than the price per gallon at the end of 1995. The price at the end of 1997 was $0.12 less than the price at the end of 1996, and so on.

Answer 1

Answer:

5 times

Step-by-step explanation:

First, we need to read the change in price in 2000 and 2007, from the graph.

So, the change in price in 2000 was $0.14 and in 2007 it was $0.71.

Now, we do the same thing we always do when comparing two values - we divide them. So:

0.71 / 0.14 = 5.07

Of course, we could multiply these values with 100, in order to avoid decimal numbers. Then we would get:

71 / 14 = 5.07

We could also divide this in the form of fractions:

71/100 / 14/100 = 5.07

There are several ways we could divide rational numbers, but the result will always be the same.

Change in price in 2007 was around 5 times greater than the change in 2000.
