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

Find out what is the price of 9 packs of spaghetti
Multiply the unit rate by 9

therefore
The price of 9 spaghetti packs is $72

It travels 65.2 miles in one hour. To calculate the rate, you use the equation distance/time=rate. So, you divide 97.8 (the distance) by 1.5 (the time) and you get 65.2 miles per hour, which is the answer.
