Beverage Dispenser H and Beverage Dispenser J have a total amount of 1179 mℓ of water. For Beverage Dispenser J and Beverage Dispenser K, the total amount of water is 1845 mℓ. The amount of water in Beverage Dispenser H is ⁵₈ the amount of water in Beverage Dispenser K. What is the average amount of water in the 3 beverage dispensers?
Beverage Dispenser H = 5 u
Beverage Dispenser K = 8 u 

Beverage Dispenser J + Beverage Dispenser H = 1179 --- (1)
Beverage Dispenser J + Beverage Dispenser K = 1845 --- (2)

(2) - (1)
(Beverage Dispenser J + Beverage Dispenser H) - (Beverage Dispenser J + Beverage Dispenser K) = 1845 - 1179
8 u - 5 u = 666
3 u = 666

1 u = 666 ÷ 3 = 222
Beverage Dispenser H = 5 u = 222 x 5 = 1110

Beverage Dispenser H + Beverage Dispenser J + Beverage Dispenser K = 1110 + 1845 = 2955 mℓ

Average amount of water in the 3 beverage dispensers
= 2955 ÷ 3 
= 985 mℓ

Answer(s): 985 mℓ
