Use the drawing tools to form the correct answer on the provided number line.
Daniel is buying gas for his car. Gas costs $2.50 per gallon. Daniel typically spends around $30 to fill his gas tank, with a variance of up to $3.
Write an inequality to model this situation. Then use the Inequality to display the range of possible gallons of gas that Daniel will buy.

Answer 1

The inequality that models the situation on Daniel's gas spending is 10.8 ≤ y ≤ 13.2.

What inequality shows the number of gallons purchased?

The lowest number of gallons Daniel can purchase is:

= (Mean amount spent - Variance) / Cost per gallon

= (30 - 3) / 2.50

= 10.8 gallons

The highest number that can be purchased:

= (30 + 3) / 2.50

= 13.2 gallons

The inequality will therefore be:

10.8 ≤ y ≤ 13.2.
