Question

The cost (in hundreds of dollars) of tuition at the community college is given by T=1.25c + 4, where c is the number if credits the student has registered for. If a student is planning to take out a loan to cover the cost of 15 credits, use the model to determine how much he should borrow.
T = (1.25c + 4)100 = (1.25*15 + 4)100 = $2,275.
1.25 * 15 + 4 = 18.75 + 4
