Mrs. Jones has a local bakery. Last week this expression shows how many peanut butter cupcakes she baked. 5 (2x -4) + 3(3 + 4x)
Natasha_Volkova [10]

Answers:

A: 11(2x-1)

B: 121 cupcakes

Step-by-step explanation:

<u>Part A: </u>

We have the following expression that models the quantity of cupcakes Mrs. Jones baked last week:

5(2x -4) + 3(3 + 4x)

Applying distributive property:

10x-20+9+12x

Grouping similar terms:

22x-11

Applying common factor 11:

11(2x-1) This is the simplified expression

<u>Part B:</u>

Now that we have the simplified expresion, we have to evaluate how many cupcakes did Mrs. Jones bake if x=6:

11(2(6)-1)

11(12-1)=11(11)=121 Hence, Mrs. Jones baked 121 cupcakes last week
