Question

The table shows the number of cups of caramel required for different amounts of flour in a caramel cookie recipe. The ratio of cups of caramel to cups of flour is constant.

Cups of Flour 5 10 20 25
Cups of Caramel 3 6 c 15

Let c = cups of caramel needed when using 20 cups of flour

Which proportion can be used to determine the value of c?


A.
B.
C.
D.

Answer 1

Answer:

c=12  

Step-by-step explanation:

if 3 cups of caramel is 5 cups of flour we can count/multiply by 5's t get the answer.  3:5 can be scaled from using first the cups of flour to determine how much we must scale by to get 20. Then we scale using the multiples of 3.

3:5 can be scaled to 10:12
