Answer 1

She can send 200 messages....

Explanation:

We have given:

Josephine is on a cell phone plan where she pays $20 a month plus $.10 per text message she does not want to spend more than $40 on her cell phone bill

The equation we get is:

20+0.10x<=40

Now solve the inequality:

20+0.10x<=40

Combine the like terms:

0.10x<= 40-20

0.10x <= 20

Divide both sides by 0.10

0.10x/0.10 <= 20/0.10

x <= 200

She can send 200 messages....
