seropon [69]

Answer:

<em>The programming language is not stated; however, I'll answer using Python programming language (</em><em>Se</em><em>e attachment</em><em> </em><em>for</em><em> </em><em>proper </em><em>for</em><em>mat</em><em>)</em>

tuition = 10000

rate = 0.04

for i in range(1,15):

tuition = tuition + tuition * rate

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

Explanation:

<em>The first 2 lines initializes tuition and rate to 10000 and 0.04 respectively</em>

tuition = 10000

rate = 0.04

<em>The next line iterates from year 1 to year 14</em>

for i in range(1,15):

<em>This line calculates the tuition for each year</em>

tuition = tuition + tuition * rate

<em>The next 3 lines prints the tuition for year 1 to year 10</em>

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

<em>The next 3 lines prints the tuition at the 4th year after year 10 (i.e. year 14)</em>

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))
