The amount of orange juice in a bottle is modeled by the equation y=128-8x, where y is the number of ounces of juice in the bott
Fantom [35]

Answer:

Number of servings left is bottle = 128-9x

Step-by-step explanation:

The amount of orange juice in a bottle is modeled by the equation

y=128-8x ---Eq (1)

Here y = number of ounces of juice in the bottle

and x = number of servings of juice poured from the bottle

Number of servings left is bottle =  number of ounces of juice in the bottle -number of servings of juice poured from the bottle

Thus,

Number of servings left is bottle =  y -x

Substracting x from both the sides of the above equation, we get - y-x = 128-8x-x\\y-x = 128-9x

Number of servings left is bottle = 128-9x
