Question

lep linear inequalityLisa will spend less than S38 on gifts. So far, she has spent $21. What are the possible additional amounts she will spend?Use c for the additional amount (in dollars) Lisa will spend.Write your answer as an inequality solved for c.

Answer 1

Since Lisa already spent $21 and she will spend less than $38, so we can set up an inequality for c where the value of c needs to be smaller than the difference of 38 and 21.

So we have:

`\begin{gathered} c<38-21 \\ c<17 \end{gathered}`

Therefore Lisa can spend any value smaller than $17.
