Challenge Math Weekly
Week 1
By: Kaitlyn S.
Hi guys! Welcome to Challenge Math Weekly! Every week, I post a new challenging math problem! All of my math problems have a different math skill. It’s okay if you get stumped, because every week I post a new problem, along with last week’s answer key. Feel free to print if you can’t do it in your head. Good Luck!
This Week’s Skill: Logical Reasoning
Story:
Five chipmunks named Annabeth, Bob, Cailey, Denver, and Joe lived in an area with a tree at each point. They each lived at a different point; 1; 2; 3; 4; and 5. They each also eat the same amount of acorns each week
(60 acorns), but at different times. 2, 4, 6, 12, 36 on Monday; 2, 4, 6, 12, 36 on Tuesday; 2, 4, 6, 12, 36 on Wednesday; 2, 4, 6, 12, 36 on Thursday; and 2, 4, 6, 12, 36 on Friday.
Clues:
- Bob likes to have more acorns on Friday than on Monday for a weekly ‘desert’
- Annabeth lives 3 points more than Bob
- On Monday, Cailey ate 2 times more than she did on Tuesday
- Bob lives 1 point more than Joe
- Denver is greedy and likes feasting as much as he can on Monday
- Bob’s point tree x 2 = Denver’s point tree
- Joe saves the most for hump day!
- Denver’s point tree x 3 = Cailey’s acorns on Monday
- On Friday, Cailey x 2 = Denver, Denver x 3 = Annabeth, and Annabeth 2 = Joe
- Denver’s Thursday x 2 = Denver’s Wednesday
