mini lesson - independent work/share out/discussion
1) The class must raise at least $100 to go on the field trip. They have collected $20. Write an inequality to represent the amount of money, m, the class still needs to raise. Represent this inequality on a number line.
2) The Flores family spent less than $200.00 last month on groceries. Write an inequality to represent this amount and graph this inequality on a number line.

team challenge
Fishing Adventures 1
Fishing Adventures rents small fishing boats to tourists for day-long fishing trips. Each boat can hold at most eight people. Additionally, each boat can only carry 900 pounds of weight for safety reasons.
a. Let p represent the total number of people. Write an inequality to describe the number of people that a boat can hold. Draw a number line diagram that shows all possible solutions.
b. Let w represent the total weight of a group of people wishing to rent a boat. Write an inequality that describes all that describes all total weights allowed in a boat. Draw a number line diagram that shows all possible solutions.
