A tuition scale for a state university shows an increase of $1,500 each year.

anonymous · Answer

1) letting the number of years be X we get 1500X+23000 so 1500X25= 37,500 now add the 23,000 to get $60,500.

I gave you a formula, but I'm going to repeat it.

@chad its ok :)

inkyvoyd · Answer

in an arithmetic series
an=a1+(n-1)d

anonymous · Answer

Okay so for each year the university will add $1,500 given an initial cost of $23,000. So you have to start at i = 23,000 and your n will be 25 years. then you add them up but a trick you can also do here is to multiply 25 by 1,500 and add it to $23,000.
