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 11 cups of rice?

17 cups of water

Step-by-step explanation:

Given:

Amount of water needed to cook rice (w) = 1.5 r + 0.5

Number of cups of rice to be cooked = r

Number of cup needed to cook rice = w

Find:

Number of cups of water needed to cook 11 cups of rice:

Computation:

Amount of water needed to cook rice (w) = 1.5 r + 0.5

We know that , Number of cups of rice to be cooked = r = 11

So,

w = 1.5 r + 0.5

w = 1.5 (11) + 0.5

w = 16.5 + 0.5

w = 17

Therefore, 17 cups of water needed to make 11 cups of rice.
