From Cynthia:
Hi I was wondering if their was a shorter way to figure out this problem...
The answer has to be in scientific notation.
A machine in a soft drink bottling factory caps 3 bottles per second.
How many bottles can it cap in 15 hours?
3,600 (forgot how I got that) multiplied by 15= 54,000
54,000 multiplied by 3 = 16,2000
answer 1.6times 10^5
