Question

1. Alexis needs to save at least $1,100 to buy a new laptop. So far she has saved $400. She makes $12 an hour babysitting.inequality_____________

Answer 1

Let:

x = number of hours babysitting

So far she has saved $400, and she needs to save at least $1100

Therefore, the inequality which represents this situation is:

`400+12x\ge1100`

In case you need to solve for x:

`\begin{gathered} \text{Subtract 400 from both sides:} \\ 12x\ge1100-400 \\ 12x\ge700 \\ \text{Divide both sides by 12:} \\ x\ge(700)/(12)=58.33 \\ x\ge58.33 \end{gathered}`

Therefore, Alexis needs to work at least 58.33 hours in order to buy her new laptop
