Question

Preet wants to determine the rate of change in gas prices. in week one of his study, he found the price to be $2.86 per gallon. in week five of his study, he found the price to be $3.14 per gallon. what is the average rate of change in gas prices, based on the data collected by preet?

Answer 1

$0.07 per week

================

To find the average rate of change in gas prices, we need to calculate the difference between the prices in week one and week five, and then divide that by the number of weeks.

In this case, the price in week one is $2.86 per gallon, and the price in week five is $3.14 per gallon.

Therefore, the difference in price is:

• $3.14 - $2.86 = $0.28

The number of weeks between these two prices is:

• 5 - 1 = 4 weeks

So, to find the average rate of change, we divide the difference in price by the number of weeks:

• $0.28 / 4 = $0.07 per week
