Complicated Billing

Here is the new version of the program:

' Improved Restaurant Bill calculator
'
PRINT "Enter the total before tax:"
INPUT TOTAL

LET TAX = TOTAL * 0.05    ' 5 percent tax
LET TIP = TOTAL * 0.15

PRINT "The tax is:", TAX
PRINT "The tip is:", TIP
PRINT "Please pay:", TOTAL + TAX + TIP
END

(The tax on a restaurant bill in a big city can be more complicated than a percentage of the total. The previous version of the program might actually be more practical.)

Billing can get complicated. Consider a photocopy shop that has the following charges:

• $0.05 to photocopy one page.
• $0.03 per staple.
• 5% tax on the total.

Say that you want to make several copies of a booklet. The booklet has a number of pages held together with one staple.
