Answer:
[tex]\frac{3}{4}[/tex] sugar is in one ounce of the drink.
Step-by-step explanation:
Unit rate is defined as the rate are expressed as a quantity as 1 such as 3 meter per second or 4 miles per hour.
As per the statement:
A 14 ounce energy drink contains 10 1/2 =[tex]\frac{21}{2}[/tex] teaspoons of sugar.
We have to find how much sugar is in one ounce of the drink.
By unit rate definition we have;
[tex]\text{Unit rate per ounce} = \frac{\frac{21}{2}}{14} = \frac{21}{2 \cdot 14}[/tex]
⇒[tex]\text{Unit rate per ounce} = \frac{21}{28} = \frac{3}{4}[/tex]
Therefore, [tex]\frac{3}{4}[/tex] sugar is in one ounce of the drink
