Under his cell phone plan, Kevin pays a flat cost of $60.50 per month and $3 per gigabyte. He wants to keep his bill under $95 per month. Which inequality can be used to determine x, the maximum number of gigabytes Kevin can use while staying within his budget?

Respuesta :

[tex]3x\text{ + 60.50 }<\text{ 95}[/tex]

Here, we want to get the maximum number of gigabytes

We have this as follows;

The fixed cost (flat cost) is $60.50 per month

The variable cost per gigabyte is $3 per gigabyte

Now, he wants to keep the bill under $95; that means the cost cannot exceed $95

Let the number of gigabytes be x; at $3 per gigabyte; the total is ;

[tex]\text{ \$3 }\times x\text{ = \$3x}[/tex]

Adding this to the flat cost;

[tex]3x\text{ + 60.50}[/tex]

Both of this is less than $95

Thus, we have;

[tex]3x\text{ + 60.50 }<\text{ 95}[/tex]
