Since the geometric series is not long we can pair up the number

20 + 29 = 49
21 + 28 = 49
22 + 27  = 49
23 + 26 = 49
24 + 25 = 49
Since we made 5 pairs of 49, the answer is 245.  (49 x 5)

1. To do this, you want to divide 1560 by 24.  This gives you 65.  The bottle fills 65 bottles per hour.
2. To do this divide 4290 by 78.  The result is 55.  It would take the groundskeeper 55 hours to drain the pond.  
3. They are similar because you break up pieces of the number and then you combine them.

If 18 is added to a certain number and the sum is divided by 6, the result is 1 more than 14 of the original number. Find the original number.

The original number is 72 


(18+x)/6 = 1+14 
1/6x + 3 = 1 + 14 (Distribute)
1/6x + 3 = (1+14) (Combine Like Terms)
1/6x + 3 = 15 
        - 3 = -3          (Subtract 3 From Both Sides)
1/6x = 12 
(1/6x)*6 = 12 * 6  (Multiply Both Sides By 6)
x = 72
