Erin baked 60 cookies with 6 scoops of flour. With 8 scoops of flour, how many cookies can Erin bake? Solve using unit rates.

Question

cookies

Answer 1

To find out how many cookies Erin can bake with 8 scoops of flour using unit rates, first, we need to determine the unit rate of cookies per scoop of flour from the initial information provided.

Erin baked 60 cookies with 6 scoops of flour. We can find the number of cookies per scoop of flour by dividing the total number of cookies by the number of scoops of flour:

$$\text{Cookies per scoop}=\frac{60\text{ cookies}}{6\text{ scoops}}=10\text{ cookies per scoop}$$

Now that we know Erin can make 10 cookies for every scoop of flour, we can find out how many cookies she can bake with 8 scoops of flour:

$$\text{Cookies with 8 scoops}=10\text{ cookies/scoop}\times 8\text{ scoops}=80\text{ cookies}$$

Thus, with 8 scoops of flour, Erin can bake 80 cookies.
