Noah prepares large batches of sparkling orange juice for school parties. He usually knows the total number of liters, t, that he needs to prepare. Write an equation that shows how Noah can find S, the number of liters of soda water, if he knows t.

Step-by-step explanation:

Given:

Number of liters of soda water = S

Total number of liters of sparkling juice = t

Let a be the number of liters of orange juice

Total number of liters of sparkling juice, t = liters of orange juice + liters of soda water

= 4a + 5 × S

Since a = S,

t = 4S + 5S

t = 9S

S = t/9

answer is b
