Question

Suppose that to send a telegram it costs $2 for the first 10 words in the telegram and Y cents for each additional words.

a. Write an equation to find the cost C of a telegram 26 words long.

b.Solve this equation for Y.

PLZ show me how to do this

Answer 1

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.

Answer 2

why 200 instead of 2?

Answer 3

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.

Answer 4

ooohhhh ok thant makes cents. lol No Pun Intended ;)
