Models Using the distributive property: (2 ● x) - (2 ● 3) = 2x - 6 This shows two groups of (x-3) This shows 2 x’s - 6

Models 6.9A The 6 th grade students sold potted flowers and potted vegetables to raise money for a class trip. They raised $289 for the trip. Sales of flowers raised $153. Let v be the number of dollars raised selling vegetables. Which bar diagram and equation model the problem? vegetables + flowers= $289 v = $289

6.9A 6.10B Angelo’s pet rabbit weighs 1 pound less than the weight of Carmen’s pet rabbit. Angelo’s rabbit weighs 9 pounds. Which equation can be used to find w, the weight of Carmen’s pet rabbit? 9 = w = w – 1 9 – w = 1 w + 9 = 1 Checking to see if it makes sense: if Angelo’s rabbit weighs 9 pounds and is one pound less than Carmen’s, then you would have to add one pound to his 9 pound rabbit to equal Carmen’s. w – 1 one pound less than

A group of 4 friends is planning a fun day trip. A raft trip costs $6 per person plus $5 for transportation of the raft. An amusement park costs $14 per person. A hot air balloon ride costs $30 per person, but they have a $40 group discount coupon. ActivityCost ($) Raft Trip Amusement Park Balloon Ride The table shows equations for the total cost of each activity for n people. Which activity should they choose if they want to spend exactly $29? Raft trip plug in 4 and it = 29! Amusement park not reasonable Balloon ride plug in 4 and it =80 Not here
