Before the last school year began, it was estimated that the average discretionary personal expenses each school year for a student attending a 4-year public college were $2,110. this past summer ashley decided to poll seven of her friends attending a 4-year public college because she thought that estimate was low. she made a list of their actual school-year expenses: $2,800, $1,990, $2,005, $2,400, $1,860, $2,200, $2,000 what is the mean of her friends' personal expenses? round your answer to the nearest cent. is the average higher or lower than the estimate? what would ashley's actual personal expenses for that school year have to be so that her amount and her friends' amounts together would have an average of $2,110?

the correct answer is a.) bc< mn 5 stars if this you : )

i am pretty sure

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
