An enrollment slip indicates a specific down payment based from the number of units enrolled by a student as follows :

Question

For number of units from 1 to 9, down payment is Php 5000; for number of units from 10 to 15, down payment is Php 10,000; and a down payment of Php 15,000 gor units from 16 to 21

Answer 1

D=downpayment in Php, x=number of units. Multiline function is:

D=5000 for 1≤x≤9

D=10000 for 10≤x≤15

D=15000 for 16≤x≤21

This is just a mathematical representation of the words of the text.

Were you looking for a single function?

Unfortunately, the images are inaccessible to me, probably because they’re on a local server. You could try photographing and uploading the photos to the site server (button for doing this is the photo symbol above to the left of the f symbol in the tool bar).
