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 money did
she start with?
and what was the cost of each
purchase?
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
