In dollars, Rick will have in his wallet after buying X boxes of tissues Which solutions are the equivalent indicate that Rick would be spending more than the $21 he has in his wallet?

Answer 1

We will have the following:

Since we are given:

`y=-1.75x+21`

Then the solution that would indicate he is spending more than he has would be:

`(16,-7)`

That is:

`y=-1.75(16)+21\Rightarrow y=-28+21\Rightarrow y=-7`
