Question

For 1993-1994, the average cost of tuition and fees at public four-year universities was $2231
for full-time in-state students. Twenty years later, it had increased 320%.
To the nearest dollar, what was the approximate cost for 2013-2014?

Answer 1

To determine the increase rate, divide 320% by 100% = 3.2

 

Current value = Original value x Rate of increase

 

C = $2231 x 3.2

 

C ≅ $7139
