Abigail collected more, she collected 87.5 lb
they collected 107.5 pounds together

For an individual die roll, the probability of rolling 6 is \dfrac{1}{6}
6

.
Effectively, this problem is asking for P(\text{1st roll is 6}\cap\text{2nd roll is 6})P(1st roll is 6∩2nd roll is 6).
Using the rule of product, this is:
\dfrac{1}{6}\times\dfrac{1}{6}=\dfrac{1}{36}

210 days* (1 week/ 7 days)* (50 inches/ 100 weeks)= 15 inches.
(Note that the units cancel out so you get the answer)
Final answer: 15 inches~
