1   Just put in '3' for 'x' in the equation and do the calculation.....   OK   Need more help than that?

 

2  Year since 2010  is   2018-2010 = 8     put this value in for 't' and calculate your answer....   Need more help?

Ok, so according to what you said, I got choice C (6220 lb/ft^2) for question 1 and for question 2 I got 406.6 which is aprrox 407,000, which is basically choice B for question 2.

 

Is that correct?
