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
To determine how much the student should borrow, we need to substitute the value of c (the number of credits) into the equation T=1.25c + 4.
Given that the student is planning to take out a loan to cover the cost of 15 credits, we can substitute c = 15 into the equation T=1.25c + 4.
T = 1.25(15) + 4
T = 18.75 + 4
T = 22.75
So, the student should borrow $22.75 hundred dollars to cover the cost of 15 credits.
