The answer should be x=133
If both containers of orange juice are being sold at the same unit rate, the ratio of ounces to dollars would be the same for the two.
solve the equation by making an inequality:
96 oz. is to $4.80, as 128 oz. is to x
96/ 4.80 = 128/ x
cross multiply 128 and 4.80 to get 614.4
next divide the 614.4 by 96
to get an answer of 6.4
answer: $6.40

Step-by-step explanation:
In linear models there is a constant additve rate of change. For example, in the equation y = mx + b, m is the constanta additivie rate of change.
In exponential models there is a constant multiplicative rate of change.
The function of the graph seems of the exponential type, so we can expect a constant multiplicative exponential rate.
We can test that using several pair of points.
The multiplicative rate of change is calcualted in this way:
[f(a) / f(b) ] / (a - b)
Use the points given in the graph: (2, 12.5) , (1, 5) , (0, 2) , (-1, 0.8)
[12.5 / 5] / (2 - 1) = 2.5
[5 / 2] / (1 - 0) = 2.5
[2 / 0.8] / (0 - (-1) ) = 2.5
Then, do doubt, the answer is 2.5
