Question

Patricia made the following two claims:



Claim 1: Tarp D is thicker than tarp B before any folds are made.
Claim 2: The thickness of tarp B will exceed the thickness of tarp D after a certain number of folds.


Which TWO statements BEST evaluate Patricia's claims?



A.
Claim 1 is correct because tarp D is
3
mil thicker than tarp B before any folds are made.

B.
Claim 1 is correct because tarp D is
6
mil thicker than tarp B before any folds are made.

C.
Claim 1 is not correct because tarp B is
2
mil thicker than tarp D before any folds are made.

D.
Claim 2 is correct because after
2
folds tarp B is already
4
mil thicker than tarp D.

E.
Claim 2 is correct because after
3
folds tarp B is already
8
mil thicker than tarp D.

F.
Claim 2 is not correct because tarp D is increasing in thickness by
8
mil each fold while tarp B is only increasing by
2
mil each fold so tarp B will never exceed the thickness of tarp D.

Answer 1

B and F.

Explanation: Tarp D is 8 mil and tarp B is 2 mil, so D is 6 mil thicker than B (choice B). Folding doubles the thickness of each tarp, so after each fold D increases by 8 mil and B by 2 mil; their ratio stays 4:1, so B can never exceed D (choice F).
