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?
Let's think: 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.

A carton of ice cream contains 10 scoops each. Mary has 3 cartons of ice cream, one chocolate, one strawberry and one vanilla. Ethan wants one scoop of vanilla and one of chocolate. Lucas, Danny and Connor all want 2 scoops of chocolate. Olivia would like a scoop of vanilla and one of strawberry. Shannon wants twice as much as Olivia. How many scoops of ice cream will be left?
Let's think: The total number of scoops of ice cream that Mary has is 3 cartons * 10 scoops = 30 scoops of ice cream. Lucas, Danny and Connor will eat 2 scoops * 3 people = 6 scoops of ice cream. Shannon will eat 2 * (1 vanilla + 1 strawberry) = 4 total scoops of ice cream. Combined the kids will eat a total of 2 + 6 + 2 + 4 scoops = 14 scoops of ice cream. Mary will have 30 scoops - 14 scoops = 16 scoops of ice cream remaining.. The answer is: 16.

The sky currently has 4 times as many cirrus clouds as cumulus clouds, and 12 times as many cumulus clouds as cumulonimbus clouds. If the sky currently has 3 cumulonimbus clouds, how many cirrus clouds are in the sky at this moment?
Let's think: The sky has 3 * 12 = 36 cumulus clouds. The sky has 4 * 36 = 144 cirrus clouds.. The answer is: 144.
