The equations that represents each of your options:  Sprint: x  Verizon: x  Cingular: 0.75x  Note: The cent we divided by hundred, because we have dollar, so we should do that.

1. During what interval dose the SPRINT offer the best deal? From (0,0) to (25,30) 2. During what interval dose the CINGULAR offer the best deal? From (0,0) to (10,5) 3. During what interval dose VERIZON offer the best deal? From (25,56) to (50,60) 4. What if you talked for an average of 100 minutes per month? CINGULAR

5. What if you talked for an average of 200 minutes per month? SPRING 6. When do SPRINT and VERIZON charge the same rate and what is the rate? (145,70) 70 Dollars per month. 7. How do you choose which plan is best for you? I choose that fits my need by calculating my average calling time.

1. On Monday you counted 48 tricycles wheels. a. How many tricycles were in the shop? 48/3 = 16 tricycles b. Write an algebraic equation that shows the relationship between the number of wheels (w) and the number of tricycles (t). 3 times w is t.

2. ON Wednesday you received new wheel. You need to install at least 50 wheels on that day. a. You have installed wheels on 5 tricycles so far. How many bicycles do you need to install wheels on to attain at least 50 wheels 50/2 = 25 bicycles. b. Write an inequality that represents the situation on the day. x≥50
