C=200+(W-10)Y
C represents cost, W represents total words, Y represents cost for additional words.
For a, we simply put in 26 for W, which gets us C=200+16Y. To solve this equation for Y, we subtract 200 from both sides and then proceed to divide both sides by 16.

why 200 instead of 2?

anonymous · Answer

Because the prompt said that Y was measured in cents, and we want them to be measured the same, so we did 200 cents instead of 2 dollars. If it had said that Y was measured in dollars, we would have used 2.
