we start by looking at the graph. the line shown goes through these points perfectly:
(2, 0.5) (4, 1) (6, 1.5) (8, 2)
and so on. now we see if any of these are included in the tables below.
there aren’t any decimals or fractions in any of the tables, so we just look for (4, 1) and (8, 2) as listed in the tables. we find that d includes those points and continues the trend with the other points listed.
18% of 420 is 75.6. Multiply that by 63 to get 4762.8. 420 multiplied by 63 equals 26460. 26460 plus 4762.8 is 31222.8. 31222.8 divided by 63 is 495.6. So the answer is $495.60 per year.
