A candy store's specialty is taffy. Customers can fill a bag with taffy and the price is based on how much the candy weighs. The store charges $2 for 10 ounces of taffy. 9-55 HW eTool (Desmos). Homework Help ✎

Copy the table below and fill in the missing values. Add three more entries.

**Amount of taffy (ounces)**2

5

10

12

15

20

**Price ($)**$2

$4

Graph the values in the table. Let

*x*represent the number of ounces and*y*represent the price in dollars.Is this situation proportional? Explain your

**reasoning**.What is the slope of the line you graphed? What information does the slope tell you?

Try writing a proportion equation.

Solve for *x*.

Does the price per ounce stay the same no matter how many ounces of taffy is bought?

Notice that the graph makes a straight line and intersects (0,0).

The slope, 0.2, tells you that the price of taffy per ounce is $0.20.
