Nala can spend no more than $150 per month on gasoline. She has already purchased $60 in gas this month. Which inequality can be used to find the maximum number of fill-ups she can purchase during the rest of the month, assuming each fill-up costs $30

Respuesta :

The inequality that can be used to find the maximum number of fill-ups she can purchase during the rest of the month, assuming each fill-up costs $30 is 3 fill-ups

Inequality

  • Amount Nala can spend on gasoline = $150
  • Amount of gasoline Nala purchased = $60
  • Cost of each fill up = $30
  • Maximum number of fill ups = x

150 ≤ 60 + 30x

150 - 60 ≤ 30x

90 ≤ 30x

divide both sides by 30

90 / 30 ≤ x

3 ≤ x

x ≥ 3

Therefore, the inequality that can be used to find the maximum number of fill-ups she can purchase during the rest of the month, assuming each fill-up costs $30 is 3 fill-ups
