Answer:

Option B. $72, because the price of each pack is $8

Step-by-step explanation:

Looking at the double number line we have that

The price of 2 packs of spaghetti is $16

The price of 4 packs of spaghetti is $32

The price of 6 packs of spaghetti is $48

The price of 8 packs of spaghetti is $64

To find out he units rate, divide the price by the number of packs

[tex]\$16/2=8\frac{\$}{pack}[/tex]

Find out what is the price of 9 packs of spaghetti

Multiply the unit rate by 9

[tex]8\frac{\$}{pack}(9\ packs)=\$72[/tex]

therefore

The price of 9 spaghetti packs is $72
