Two Step Solving Inequalities

Nick had $26.50 to spend at the fair. Admission to the fair was $8.50 and rides cost $1.50 per ticket. Which inequality and solution represents how many ride tickets Nick can purchase?

• 8.50 + 1.50x < 26.50; Nick can purchase more than 12 tickets

• 8.50 + 1.50x > 26.50; Nick can purchase more than 12 tickets

• 8.50 + 1.50x ≤ 26.50; Nick can purchase no more than 12 tickets

• 8.50 + 1.50x ≥ 26.50; Nick can purchase no more than 12 tickets

Lionel wants to buy a belt that costs $22. He also wants to buy some shirts that are on sale for $17 each. He has $80. What inequality can you write to find the number of shirts he can buy? Identify what your variable represents.

• 22 + 17n < 80; n = the cost of the belt

• 80 + 17n > 22; n = the cost of the shirts

• 22n + 17 < 80; n = the number of belts he can buy

• 22 + 17n ≤ 80; n = the number of shirts he can buy

Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese costs $1.29. Write an inequality to find the numbers of bagels Nick can buy. Identify what your variable represents.

• 0.75 + 1.29N < 7.00; n = the number of bagels Nick can buy

• 0.75n + 1.29 < 7.00; n = the number of bagels Nick can buy

• 0.75n - 1.29 < 7.00; n = the number cream cheese Nick can buy

• 0.75 - 1.29n > 7.00; n = the number of bagels Nick can buy

Lincoln Middle School plans to collect more than 2,000 cans of food in a food drive. So far, 668 cans have been collected. Write an inequality to find numbers of cans the school can collect on each of the final 7 days of the drive to meet this goal. Identify what your variable represents.

• 668 + 7n > 2,000; n = the average number of cans each day

• 2,000 - 7n > 2,000; n = the number of students

• 668 + 7n > 2,000; n = the average number of cans each day

• 2,000 + 7n < 668; n = the number of people donating
