You have to find the common denominator for the two most frequent lengths which would be 8. Then you have to multiply the numerator by the same number you multiplied the denominator by and you would get 2/8 plus 3/8 and you get 5/8
The answer is choice C. The reason why is because f(2010) = t(2010). The outputs of the f(x) and t(x) functions are the same when the input is x = 2010. In this case, the output is 740.
