4vir4ik [10]

the number of cups of red Lin needs is 27 cups

Explanation:

number of parts of red = 3

number of parts of yellow = 2

the ratio of red to yellow = 3:2

when lin's number of cups of yellow = 18

let the number of cups of red = x

3 red = 2 yellow

x red = 18 yellow

cross multiply:

3(18) = 2(x)

54 = 2x

divide both sides by 2:

54/2 = 2x/2

x = 27

Hence, the number of cups of red Lin needs is 27 cups
