Answer:

' 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
LET CANS = SQUAREFEET / 80
PRINT "Size of carpet = ", SQUAREFEET, "Required cans = ", CANS
END

Temporary Variables

Sometimes variables are used inside a program to build up to the answer. They are used somewhat like "scratch paper" to hold a step along the way to the result you want. The final PRINT statement might not use them.

Consider the following problem: On Valentine's Day you receive a box of 200 chocolates. The packaging makes the following claims:

35 percent of the chocolates are filled with caramel.
25 percent of the chocolates are filled with coconut.
20 percent of the chocolates are filled with cherry cream.
10 percent of the chocolates are filled with nuts.
the remaining 10 percent are solid chocolate.

You dislike coconut and cherry cream chocolates, and won't eat them.

QUESTION 16:

Will the following program correctly calculate how many chocolates you eat and how many you discard? (Remember that both upper and lower case letters can be used in names for variables, so all the names are correct.)

' Valentine's Day Treat
'
LET TotalChocolates = 200
LET DiscardPercent = 25 + 20
LET Discard = TotalChocolates * (DiscardPercent / 100)
LET Eaten = TotalChocolates - Discard
PRINT "You will eat", Eaten, "chocolates and throw away", Discard, "chocolates."
