Question

The very rigorous medical program at a local university has a 25% drop out rate for each year. If the school admits 1,000 freshmen, how many diplomas will need to be ordered 4 years later?

Answer 1

So each year, a quarter of 1000 freshmen will drop out. So:

Year 1: \(\ \huge 1000 \times .25 = 250, so 750 remain \).
Year 2: \(\ \huge 750 \times .25 \approx 188; so 562 remain \).
Year 3: \(\ \huge 188 \times .25 = 47, so 141 remain \).
Graduation Year: \(\ \huge 141 \times .25 \approx 35, so 106 remain \).

So, the school will need \(\ \huge 106 \color{green} diplomas for this class \).
