Question

You earn $9.20 per hour at your

summer job. Write and solve an inequality that
represents the number of hours you need to work
in order to buy a smart phone that costs $299.

Answer 1

9.2h > 299

If H represents the number of hours you work you must multiple that by the amount you make per hour. If the total is greater than or equal to the cost of the phone, you can buy it.

9.2h/9.2
`\geq` 299/9.2 Now that we have the equation we can divide each side by 9.2 to isolate the variable.

h
`\geq` 32.5

Hope this helps.

Answer 2

32.5
