Math 123 Quantiative Reasoning chapter Linear models

1.) According to the Ivy Tech website, students will pay a $60 technology fee and $121.50 per credit hour for spring 2014.

a) Set up a linear model to calculate a student’s bill based on this information.

b) The independent variable in m model is_____ and it represents_______

c) The dependent variable in my model is_______ and it represents_______

d) Use your model to determine how many credit hours a student is taking if his bill is $1639.50?

1Total bill = Technology fee+ no of hour * per hour credit

Bill = t + n*c

2.Independent variable is ' t' and it represents technology fee .

3The dependent variable in my mode is 'n' and it represent no of hour.

1639.50 = 60 + n * 121.50

1639.50 - 60 = n * 121.50

1579.5 /121.50=n

n=13
