Answer:
They have raised $500 so far
Step-by-step explanation:
Multiply $2500 by 20% (aka 0.2) and you get $500
(They need to raise another $2,000 still)
means to say that for any given 
, we can find 
such that anytime 
(i.e. the whenever 
is "close enough" to 5), we can guarantee that 
(i.e. the value of 
is "close enough" to the limit value).
What we want to end up with is
Dividing both sides by 3 gives
which suggests 
is a sufficient threshold.
The proof itself is essentially the reverse of this analysis: Let be given. Then if
and so the limit is 7. QED
1.9 because if the number after it is lower then it is just the first number
Answer:
0.75 lbs.
Step-by-step explanation:
Okay, this one is more simple. To find the weight of each book, You have to solve this division problem:
15/20
If you divided it the other way around, you would be saying each book weighed 1.33 pounds. That wouldn't be correct because then you would have over 20 lbs. of books, when you only have 15.
So, the answer is 0.75 pounds.
Step-by-step explanation:
200,000 X 50,000 = 100000000
