5.)Find the unit rate

a.2 pens for 94 cents.

I used fraction. Cents/Pens

94/2 I divided 94 and 2 by 2. And you should get 47 over 1 like this. 47/1.

b. Delia was paid 35$ for 5 hours of babysitting. how will she get 3 hours.
Money/ Hours =35/5. I divided each side 5. And you should get 7/1. And then I multiplied both sides by 3. You should get 21/3.
