Answer:
$60
Explanation:
The savings of Andries is $120 and his grandfather offered that he would give 50% of the amount he saved.
50% is actually just half of a given amount. So the short way to do this is just half the saving of Andries.
![(\$120)/(2) = \$60](https://img.qammunity.org/2020/formulas/mathematics/high-school/x18r0rrqu2trr13yh7mywh7dblz5zq64v7.png)
You can also think of it this way:
![50\%=(50)/(100)](https://img.qammunity.org/2020/formulas/mathematics/high-school/b8x5xz7hkyat6w0tyaoljtkthmujysk91z.png)
So we multiply that to the amount saved to solve for what is 50% of 120.
![\$120*(50)/(100) = (\$6000)/(100)=\$60.00](https://img.qammunity.org/2020/formulas/mathematics/high-school/3hvlczopr8hcao9ekphtw9l78t4jg456w9.png)
