Beverage Dispenser Y and Beverage Dispenser Z have a total amount of 3025 mℓ of water. For Beverage Dispenser Z and Beverage Dispenser A, the total amount of water is 3927 mℓ. The amount of water in Beverage Dispenser Y is ³₅ the amount of water in Beverage Dispenser A. What is the average amount of water in the 3 beverage dispensers?
Beverage Dispenser Y = 3 u
Beverage Dispenser A = 5 u 

Beverage Dispenser Z + Beverage Dispenser Y = 3025 --- (1)
Beverage Dispenser Z + Beverage Dispenser A = 3927 --- (2)

(2) - (1)
(Beverage Dispenser Z + Beverage Dispenser Y) - (Beverage Dispenser Z + Beverage Dispenser A) = 3927 - 3025
5 u - 3 u = 902
2 u = 902

1 u = 902 ÷ 2 = 451
Beverage Dispenser Y = 3 u = 451 x 3 = 1353

Beverage Dispenser Y + Beverage Dispenser Z + Beverage Dispenser A = 1353 + 3927 = 5280 mℓ

Average amount of water in the 3 beverage dispensers
= 5280 ÷ 3 
= 1760 mℓ

Answer(s): 1760 mℓ
