Camping Adventure
Math Story by Claudette J. Young
Last Saturday Wendy invited five friends for a
weekend campout in her backyard. She paced and
fretted, waiting for Saturday to arrive. When it did,
Wendy’s mother took her to the grocery store early that
morning.
“We need to buy the food you girls will have on
your campout,” her mother said.
At the store, they bought:
•
•
•
•
•
•
16 ounce package of ten hot dogs @ $1.49
11 ounce package of hot dog buns @ $1.98
14.4 ounce package of graham crackers @ $1.25
10 ounce package of marshmallows @ $1.89
39 ounce box of chocolate bars @ $3.09
16 ounce bag of potato chips @ $3.29
Wendy’s mother paid for the food and they left the store to go home.
That evening Wendy and her friends got ready for their cookout, Wendy pulled the
food from the cooler and began opening packages. Each paper plate had a hot dog
bun waiting to be filled. Six roasting sticks sprouted hot dogs and hovered over low
flames in the fire pit.
After the girls ate their first hot dogs, Wendy realized that there were only four hot
dogs left. There wasn’t enough for everyone to have a second one. She asked how
many girls wanted another hot dog and three girls called out. Whew! Those who wanted
one could have one.
When Wendy looked at the buns, she found only
two buns were left. She told the three girls who readied
their roasting sticks that one of them wouldn’t have a
bun. One girl laughed and said that always happened at
her home and she could eat her “dog” without a bun.
When it came time for smores, each girl had two.
Everyone went to sleep that night satisfied with the
food, the singing around the campfire, and their
friendship.

The Case of the Troublesome Triplets
Detectives, I need your help solving a tricky case.
This morning at 10 a.m., one of the Troublesome
Triplets stole $100 from a teller at the Cashflow
Bank. The infamous triplets, Doris, Dottie, and
Demi, look so much alike, the teller couldn’t identify
which one took the money.
I wanted to be sure I didn’t accuse the wrong triplet
of stealing, so I alerted shopkeepers across town
to let me know when one of the sisters bought
anything. Right away, the phone was ringing off the
hook.
“Math Maven, this is Flo from Fad Fashion. One
of those Troublesome Triplets was just here. She
bought a $60 red dress at half price during our
sale.”
The next call was from Nelly, the owner of the Nut
House. Nelly reported that one of the Troublesome
Triplets had bought 5 pounds of peanuts at 49
cents per pound.
Then Earl, down at the bus station, called. One of
the Troublesome Triplets had just paid 85 cents an
hour to store her shopping bags for two hours.
The next call was from Brad at the bowling alley:
“Math Maven, two of the triplets just left the bowling
alley. They each paid $7. They’ve been bowling
since nine o’clock this morning.”
Before long, Trixie called from the diner: “Math
Maven, you should come quickly! The Troublesome
Triplets are all here. They just sat down for lunch.”
I arrived at the diner as the three sisters were
finishing dessert.
“Well, hello ladies. One of you has had a very busy
shopping day. . .with the $100 you stole from the
bank!” I exclaimed.

The Case of the Troublesome Triplets
“Math Maven, you’re wrong. We were bowling all
day,” said Doris.
“Two of you were bowling, but one of you robbed
the Cashflow Bank this morning,” I said. “I can
prove it. Show me the money you have in your
pockets!”
“This is outrageous! We will not empty our
pockets!” exclaimed Demi.
“I want my lawyer!” screamed Dottie.
“Then all three of you are coming down to the
police station,” I commanded.
With that, Doris, Dottie, and Demi each emptied
the contents of their pockets onto the table.
