Question 8:
Here's something slightly
different. It comes from a Day Calendar entitled
'365 Brain Puzzles' by Dr. Abbie F. Salny.
Jennifer
went shopping for birthday presents.
She spent half of what she had, plus $5, for a
blouse;
then half of what was left, plus $5, for a
cookbook;
then half of what was left, plus $5, for
stationery.
Jennifer had nothing left. How much did she
start with?
If you got
confused with all the text you could make a rough
sketch or chart. This may help you to see it
clearer.
Tip:
Let
'x' equal the total money Jennifer
spent.
The equation
can be:
'x' = Cost of
the blouse + Cost of the cookbook + Cost of the
stationery
