Question

The telephone company offers two billing plans for local calls. Plan 1 charges ​$ per month for unlimited calls and Plan 2 charges ​$ per month plus ​$ per call.

Answer 1

Answer and Step-by-step explanation:

Let us assume the number of calls be x

So

For Plan 1

Total monthly charges is $24 for unlimited calls

For Plan 2

There is a charge of $16 and $0.04 per call

We can write as

= 0.04x + $16

a)  Now the inequality equation is

0.04x + $16 > $24

0.04x > $8

x > 200

b)   Now if there are more than 200 calls than Plan 1 is more economical as compared with plan 2
