Answer: D, When the constants are perfect squares.

Step-by-step explanation:

the nutrition facts label from a 12 oz can of soft drink is shown below. Note that a serving of the soft drink is defined as 8 o

The correct answer is C. 65

Explanation:

The serving size of the soft drink is 8oz, besides this, the amount of sugar for this serving size according to the label is 26 grames. Now, to calculate the amount of sugar in 20oz, one of the simplest methods is to use a rule of three, because three values are known, and one is missing. The process is shown below:

1. Write the known values and use x to represent the unknown values

8 oz = 26 grames of sugar

20 oz = x

2. Use cross multiplication (this means multiply 8 x 6) and divide it into the remaining value

$x = \frac{26 x 20}{ 8}$ or x = 26 x 20 / 8
