In the past 4 years, a sporting goods store had two yearly losses of $13,000 and $21,000 and two yearly profits of $129,000 and $310,000.
what was the net profit or loss over 4 years?
a.
$405,000
b.
$473,000
c.
−$473,000
d.
−$405,000

So we want to know what is the money lost or profited in the 4 year period of the store if the money lost for two years was 13000$ and 21000$ and money profited was 129000$ and 310000$. To get the answer we simply add the annual losses and profits: -13000$-21000$+129000$+310000$=405000$. So after 4 years the overall profit is 405000$.

I’m confused as to what you are asking 66 2/3 percentage wise
