Answer: $0.70 per cookie
Which is the same as saying 70 cents per cookie
=============================================================
Explanation:
The unit rate is the cost of one cookie. The term "unit" means "one".
10 cookies = 7 dollars
10/10 cookies = 7/10 dollars ...... divide both sides by 10
1 cookie = 0.70 dollars
Since one cookie costs $0.70, the unit rate is $0.70 per cookie or you can say 70 cents per cookie.
