Question

Cell plan A is $40 plus $.04 each text Cell plan B is $30 plus $.09 each text Write an inequality that shows when plan A is greater that plan B

Answer 1

Step-by-step explanation:

Let 'x' be the number of texts

The equation for the cost of plan A is:

`y_A=40+0.4x`

The equation for the cost of plan B is:

`y_B=30+0.9x`

We want:

`y_A>y_B`

Answer:

The inequality is:

`40+0.4x>30+0.9x`
