Answer the following question.
Nick's cell phone was initially empty but was then charged for 45 minutes and has reached a 25% charge. How much longer must the cell phone be charged to reach 100% charge?
Step-by-step reasoning process: The ratio between the time charged and the time to be charged is 100 / 25 = 4. To reach 100%, the cell must be charged for 45 minutes * 4 = 180 minutes. Subtracting the 45 minutes that Jimmy already used to charge the cell phone, there are still 180 - 45 = 135 minutes of charging time left.
The answer is 135.

Answer the following question.
One of Robi's new year's resolutions is to start saving. He started to save $2 in January. This is followed by $4 in February and $8 in March. If he continues this saving pattern, how much will be his total savings after 6 months?
Step-by-step reasoning process: Robi will save $8 x 2 = $16 in April. He will save $16 x 2 = $32 in May. He will save $32 x 2 = $64 in June. Hence, his total savings after 6 months will be $2 + $4 + $8 + $16 + $32 + $64 = $126.
The answer is 126.
