Andries get grandfather get offered to give him a gift of 50% of the amount of money he saved in one year. And Ray saved $120. H
sertanlavr [38]

Answer:

$60

Step-by-step 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.

\dfrac{\$120}{2} = \$60

You can also think of it this way:

50\%=\dfrac{50}{100}

So we multiply that to the amount saved to solve for what is 50% of 120.

\$120\times\dfrac{50}{100} = \dfrac{\$6000}{100}=\$60.00
