Answer:

70 dollars

1600 dollars

Step-by-step explanation:

The equation is

[tex]y=70x+1600[/tex]

where

y = Total pay

x = Number of of copies of History is Fun sold

Cost of History is Fun is 70

Rita's fixed pay is 1600

The change in Rita's total pay for each copy of History is Fun sold she earns 70 dollars.

If she sells zero copies of History is Fun then x = 0

[tex]y=70\times 0+1600\\\Rightarrow y=1600[/tex]

So, her total pay would be 1600 dollars.
