Question

Yesterday, the price of a gallon of gas at five gas stations was $3.72, $3.87, $3.78, $4.09, and $3.989, respectively, but today each gas station raised its price by $0.08. What is today's mean price of a gallon of gas at the five stations?
A. 3.97
B. 4.05
C. 3.89
D. 3.81

Answer 1

Answer:

The correct answer is A. 3.97

Step-by-step explanation:

If you start by adding 0.08(the increased price) to what the price already was for each gas station you will end up with the numbers 3.8, 3.95, 3.86, 4.17, and 4.069 and once you add all of these numbers together you shold then divide that answer by 5 because there are 5 gas stations. After you divide the numbers by 5 you should get the decimal 3.9698 and round it up to the correct answer A
