Answer 1

The mean of her friends' personal expenses for a 4-year public college is $2,179.29 when rounded to the nearest cent.

Step-by-step explanation:

The mean of Ashley's friends' personal expenses for attending a 4-year public college can be found by adding all the expenses together and then dividing by the number of friends. To calculate the mean, we use the formula: Mean = (Sum of all values) / (Number of values). In this case:

• $2,800
• $1,990
• $2,005
• $2,400
• $1,860
• $2,200
• $2,000

We add these amounts to get a total of $15,255. Then, we divide this sum by the number of friends, which is 7, to get the mean expense: Mean = $15,255 / 7 = $2,179.29.

Therefore, the mean of her friends' expenses rounded to the nearest cent i
