Writing Inequalities

ATT has a family plan of four lines for $125 and additional lines are $15 each per month. If Jason wants to spend at most $200 per month on cell phone expenses, how many additional lines can he afford? 125 + 15𝒙 ≥ 200 125 + 15𝒙 ≤ 200 125 − 15𝒙 ≥ 200 125 − 15 ≤ 200 Jannie has a budget of $200 to spend on jeans and shirts. She spends $75 on jeans. If the cost of each shirtis $19.50, how many can she buy without going over the budget? 19.50𝒙 + 75 ≤ $200 75𝒙 + 19.50 ≤ $200 19.50𝒙 - 75 ≥ $200 75𝒙 -19.50 ≥ $200 Ten more than three times a number is no more than -95. What could be the value of the number? 10 + 3𝒙 ≤ −95 10 + 3𝒙 ≥ −95 3𝒙 - 10 ≤ −95 3𝒙 - 10 ≥ −95 Matching Inequalities Match the example with the correct inequality. Joseph has 20 gallons of gas in his tank. His tank uses 6 gallons an hour. Choose the inequality that represents the length of time Joseph can drive before running out of gas. 6x ≥ 20 Joseph must sell more than 20 ice cream cones in order to make a profit. He has already sold 6 cones. Choose the inequality that represents the number of cones Joseph still needs to sell. x + 6 ﹥20 Joseph withdraws $25 each week for 10 weeks for entertainment. He wants to have more than $200 remaining by the end of the summer. Choose the inequality that represents the amount of money Joseph started the summer with. x - 250 ﹥200
