Respuesta :

100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.


It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.


The answer should be D.

y= 720x +100

A university charges a $100 application fee and $720 per month

x = the number of months

y = total cost


y = 720x + 100

[they charge $720 per month(x) plus a fee of $100]


Your answer is the last option.
