from 2007 to 2012 is only 5 years, so we can see this as a compound interest with a rate of 1.2% per annum for 5 years, so
Hello! The answer is definitely not C or D, because that's way too i God an increase for this type of setting. It increased by around 20%, because when 35 and 29 are divided and you multiply the decimal by 100, when you ignore the "1" at the front, it shows an approximate 20% increase. The answer is A.
To do this, change into common denominators. The common denominator is 21 so change the problem from 1/3 + 1/7 to 7/21 + 3/21. This gives you 10/21. It is already in simplest form.
It is 1
70+30*1=100, which is not a prime number
