7th Math 3.15

Skill and Drill 1--Solve the inequality then graph the solutions on the number line.

List out some solutions or values of y.

2y\geq8

**You MUST SYW**. Be patient, this will be graded by hand.

CFS:

#1: Accurately solves and interprets inequality

#2: Accurately graphs solution set on number line

Skill and Drill 2--Solve the inequality then graph the solutions on the number line.

List out some solutions or values of x.

-4-2x<2

**You MUST SYW for the graph**

CFS:

#1: Accurately solves and interprets inequality

#2: Accurately graphs solution set on number line

Hamilton 2--Ms. Zangrilli is promoting her new play. She starts with 300 tickets and believes that she can sell about 12 tickets per day. Her goal is to have less than 40 unsold tickets.

How many days of promoting will it take for Ms. Zangrilli to reach her goal?

CFS:

#1: Defines appropriate variable

#2: Accurately writes and solves inequality

#3: Accurately graphs solution set on number line

Meters--Parking in LA is quite expensive. Mr. Hwung's family parked their car in a garage that charges $8 per hour. If they started with $65 and want to have at least $30 left over for when they pay for dinner, what is the longest amount of time they can stay in the parking garage?

CFS:

#1: Defines appropriate variable

#2: Accurately writes and solves inequality

#3: Accurately graphs solution set on number line

SPICY--Try if you have time (optional)

Write your own word problem like in our examples. You can make it about any kind of scenario, but usually relating it to money is easiest.

Then create your own inequality, and if you have time you can solve your own story!

Solve the inequality and graph the solution set on the number line.

Make sure to show all work for credit.
