$191$ ounces and $270$ ouncesConcept Used:

The percent of change from $a$ to $b$ is defined as

  $\text{Percent Change}=\left(\frac{b-a}{a}\right)\times 100$

Calculation:

The percent of change from $a$ to $b$ is defined as

  $\text{Percent Change}=\left(\frac{b-a}{a}\right)\times 100$

Therefore, from $191$ ounces to $270$ ounces

  $\begin{array}{c}\text{Percent Change}=\left(\frac{270-191}{191}\right)\times 100\\ =\frac{79}{191}\times 100\\ =\frac{7900}{191}\\ =41.4\%\end{array}$

Therefore, the percent of change is $41.4\%$

Since, percent of change is positive. Therefore, the percent of change is an increase.
