QUESTION 15:
Modify the previous program so that it calculates the number of
cans of carpet cleaner and stores the result in a variable
called CANS.
Use the PRINT statement
to print out SQUAREFEET and
CANS and appropriate captions.
' How many cans of cleaner are required for a 12 by 17 ft carpet? ' One can will clean 80 square feet ' LET SQUAREFEET = 12 * 17 PRINT "Required cans = ", SQUAREFEET / 80 END
The number of square feet in a rectangle is the product of the width and breadth, here 12 * 17. Divide the number of square feet in the carpet by the number of square feet one can of cleaner will clean to find the number of cans needed.
The program will write out:
Required cans = 2.55
Often a program calculates several things as it runs and keeps each
result in a variable.
Only at the end does the program print out everything it has calculated
by using the variables in a PRINT statement.
Modify the previous program so that it calculates the number of
cans of carpet cleaner and stores the result in a variable
called CANS.
Use the PRINT statement
to print out SQUAREFEET and
CANS and appropriate captions.
