**will give brainliest** must show work! carly and tom mason keep records of their expenditures. they want to know hot much they spend each month, on average. their records for four months are shown below. what is their average monthly expenditure. month | expenditure january | $5,678.54 february | 3,665.77 march | 4,231.98 april | 4,768.99 a) 3,877.99 b) 4,586.32 c) 4,988.01 d) 5,001.01

To find the average of an amount of numbers, we simply add them up and divide them by the amount of numbers we have. For example, if we have 1,2, and 3 as our numbers, we can see that we have three numbers. Next, we add them up to get 1+2+3=6. Lastly, we divide 6 by the amount of numbers we have (3) to get 6/3=2 as our average. Applying that here, we see that there are four numbers. Next, we add them up using a calculator to get 5,678.54+3,665.77+4,231.98+4,768.99 =18345.28 . Finally, we divide that number by the amount of numbers we have (using a calculator) to get 18345.28/4=4,586.32, making B your answer.
