7. Example 2 Apply the Distributive Property Su is baking cookies and cupcakes. The cookies use 2 cups of sugar per batch and the cupcakes use 3 cups of sugar per batch. How many total cups of sugar are needed if she is making 5 batches of each? Method 1Multiply. Then add. 5(2) + 5(3) = 10 + 15 or 25 cups amount of sugar for cookies amount of sugar for cupcakes

8. Example 2 Apply the Distributive Property Method 2 Add. Then multiply. 5(2 + 3) = 5(5) or 25 cups. amount of sugar for one batch of cookies and one batch of cupcakes Answer: Using either method, Su needs 25 cups of sugar.

9. 1.A 2.B 3.C 4.D Example 2 A.$6.00 B.$12.00 C.$10.00 D.$18.00 A package of pencils costs $2.00 each and a package of pens costs $4.00 each. How much will Robert spend if he buys 3 packages of each?

10. Example 3 Rewrite Algebraic Expressions Use the Distributive Property to rewrite 4(x – 3). 4(x – 3)=4[x + (–3)]Rewrite x – 3 as x + (–3). =4(x) + 4(–3)Distributive Property =4x + (–12)Multiply. =4x – 12Rewrite 4x + (–12) as 4x – 12. Answer: 4x – 12

11. 1.A 2.B 3.C 4.D Example 3 A.3x – 9 B.3x – 6 C.3x – 3 D.x – 9 Use the Distributive Property to rewrite 3(x – 3).

12. Example 4 Rewrite Algebraic Expressions Use the Distributive Property to rewrite 5(x + 6). 5(x + 6)=5(x) + 5(6)Distributive Property =5x + 30Multiply. Answer: 5x + 30
