Elena is trying to figure out how many movies she can download to her hard drive. The hard drive is supposed to hold 500 gigabytes of data, but 58 gigabytes are already taken up by other files. Each movie is 8 gigabytes. Elena wrote the inequality
8x + 58 ≥ 500
and solved it to find the solution x ≥ 55.25.

1. Explain how you know Elena made a mistake based on her solution.

2a) In the cafeteria, there is one large 30-seat table and many smaller 4-seat tables. There are enough tables to fit AT LEAST 200 students.

Write an inequality whose solution is the possible number of 4-seat tables in the cafeteria.

2b) 5 barrels catch rainwater in the schoolyard. Four barrels are the same size, and the fifth barrel holds 10 liters of water. Combined, the 5 barrels can hold at least 200 liters of water.
