Alice can bake 15 cookies with each scoop of flour. With 3 scoops of flour,how many cookies can Alice bake?

Answer 1

Because the numbers of cookies and the scoops of flour are proportional, numbers of cookies/scoops of flour=15/1=x/3 (set numbers of cooks for 3 scoops of flours as x). We can calculate x=45. Therefore, Alice can bake 45 cookies with 3 scoops of flours.
