Here is a formula for the amount of water needed to cook rice. w = 1.5r + 0.5

w is the number of cups of water needed.

r is the number of cups of rice to be cooked.

(a) How many cups of water are needed to cook 7 cups of rice?

(b) How many cups of rice can be cooked with 20 cups of water?

Step-by-step explanation:

So w =water.

1 cup of water is equal to 1.5 times the volume of rice +0.5

so it'd be (11x1.5) + 0.5 for part A and for part B so you'd need to rearrange the equation which i'm not confident on .

W= (1.5 x11)+0.5

W=17

29=(1.5 x r) + 0.5

28.5=1.5r

19= r
