**a) Determine the price per bar. Give your answer in dollars and cents.**

**12/12=1 9.96/12=0.83**

**b) Explain whether your answer in part a)is a ratio or a rate.**

**It's a rate because we're comparing 2 things with different units of**

**measurement**

**Definitions:**

**Ratio**

**-a way to**

**compare 2 quantities**

**, sort of like a fraction but only sideways example: (a word ratio) pears to apples (a regular number ratio) 1:3**

**Rate**

**- when you**

**compare 2 things in different units.**
