![x*y=z](https://img.qammunity.org/2021/formulas/mathematics/high-school/9ge0b63g7oexqqwcggoi0zsa217yal5vcz.png)
x = Amount of groups
y = Amount of berries per group
z = Amount of berries total.
Substitute values:
![25*10=250](https://img.qammunity.org/2021/formulas/mathematics/high-school/lwkd4cblypquoknswsh60yojtd0tx7hj0r.png)
