The first step to determine the percentage of increase is to
compute for the difference of consumer price index in value.
231.11 (consumer price index for 2012) – 211.4 (consumer
price index for 2007) = 19.71 (increase)
To compute for the percentage of increase, you need to
compare the increase to the consumer price index for 2007.
19.71/211.4 = 9.3% increase
For 10 rows, she takes = 12 min.
So, for 1 row, she'll take = 12/10
Now, for 15 rows, it would be: 12/10 * 25 = 12/2 * 5 = 60/2 = 30
So, Your Final Answer would be 30 minutes
Hope this helps!
