Mirandas financial aide stipulates that fer tuition not exceed 1,200 if her college charges $55 regestration fee for the term plus $450 per course what is the greatest number of courses miranda can register for_ answer should be whole number.

Call the number of courses ' C '.

Whatever it is, it will cost her [ 55 + 450C ].

How many courses can she get for $1,200 ?

55 + 450C = 1200

Subtract 55 from each side:

450C = 1145

Divide each side by 450 :

C = 1145 / 450 = 2.544...

She can only register for a whole number of courses, so 2 is the limit.

That will cost her (55 + 2x450) = (55 + 900) = $955
and she'll have $245 left over ... not enough for another course.

Mirandas can sign up for 2 courses
