you will have to do decimal calculations
OpenStudy (dbzfan836):
to get your answer
OpenStudy (dbzfan836):
that is the closest you will get with integral calculation
OpenStudy (anonymous):
Can you show me step by step?
OpenStudy (dbzfan836):

i will help you for basic integral, but i am not so good in twelthes in decimal form
OpenStudy (dbzfan836):
basically, you start at 30,3
OpenStudy (dbzfan836):
then, every year John and James go up by one
OpenStudy (dbzfan836):
so a year later, John would be 4 and James 31
OpenStudy (dbzfan836):
and then a year later 5,32

so yeah the closest is 7,34
OpenStudy (anonymous):
How do you know that it is the closest?
OpenStudy (dbzfan836):
because 34/7=~4.8 . we need 5 to be the quotient, or the answer to the division.
