QUESTION 11:
The price per copy calculation inside the loop has to choose between two prices. What sort of control structure do you suppose will be used?
There are 500 sheets in a ream of copier paper. Write a program that prints a table giving the number of reams and the number of sheets.
PRINT "Number of Reams", "Number of Sheets"
FOR REAM = 1 TO 10
PRINT REAM, REAM * 500
NEXT REAM
'
END
A copy shop wants a table that shows the price for the number of copies made. The table looks something like this:
Number of Copies Price
1 0.15
2 0.30
3 0.45
. . .
50 3.50
The cost per copy is as follows:
The charge per copy depends on how many copies you make. If you make 3 copies, the rate is 15 cents per copy and the total charge is 3 * 0.15 = $0.45. If you make 10 copies, then the rate is 7 cents per copy and the charge is 10 * 0.07 = $0.70. (Usually price schedules are more complicated than this.)
Here is an incomplete program that prints the table:
PRINT "Number of Copies", "Price" FOR COPIES = 1 TO 50 calculate price per copy calculate and print total price NEXT COPIES ' END
This will be more complicated than some of our recent programs.
