Explanation:
because you're asking how to solve this, I won't say the answers to each box (but I think this might help)
you would solve this by plugging in the year (t) to the equation
(P = 0.173t - 345.8)
example:
(year = 2015)
P = 0.173(2015) - 345.8
P = 348.595 - 345.8
P = 2.795
(rounded to the nearest tenth: 2.8%)
hope this helps!!
(if there are any specific years that you want me to go through, please let me know, but I think you might figure this one out on your own :) )
