Explanation:

Step1: Set up the inequality

Let \(x\) be the number of gigabytes. The total cost is the flat cost plus the cost per gigabyte. So the inequality is \(55 + 5x<70\).

Step2: Solve the inequality for \(x\)

Subtract \(55\) from both sides: \(5x<70 - 55\), which simplifies to \(5x<15\). Then divide both sides by \(5\): \(x < 3\).

Answer:

Inequality: \(55+5x < 70\), \(x < 3\)
