All we need to do is plug in the values and check. 15*60 + 10 * 20 ≥ 1100. Is this statement true? 15 * 60 = 900 20 * 10 = 200 900+200 = 1100 Is the statement 1100≥1100 true? Yes! So, (60, 20) is a solution because 1100 is greater than or equal to 1100.
The coordinate pair (60, 20) is a solution because it satisfies the inequality. The coordinate pair (60, 20) is a solution because Ezra earns 60 x $15 = $900 mowing lawns and 20 x $10 = $200 walking dogs, for a total of $1100. Ezra can spend 60 hours mowing lawns and 20 hours walking dogs to earn enough money for the laptop.
