Question

Tia is working to get enough money to buy a new cell phone she had already saved $220 but needs to have atleast $595 to buy the phone each week at her job she saves $50 for the cost of the phone

Answer 1

Let

x ------> the number of weeks

Remember that

" at least" -----> means greater than or equal to

so

The inequality that represent this situation is

`\begin{gathered} 220+50x\ge595 \\ 50x\ge595-220 \\ 50x\ge375 \\ x\ge7.5\text{ weeks} \end{gathered}`

therefore

The minumum number of weeks is 7.5
