With Company​ Y, it costs 20¢ to connect and then 4¢ for each minute. Write and simplify an expression that represents how much more Company X​ charges, in​ cents, for n minutes
(35+5​n)−​(20+4​n)

Answer 1

Answer:

(20 + n)¢

Step-by-step explanation:

With Company X, it costs 35¢ to connect  and then 5¢ for each minute.

So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢

Again,  With Company Y,  it costs 15¢ to connect and then 4¢ for each  minute.

So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.

Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)
