Answer: The amount given by his grandfather to him = $60.
Step-by-step explanation:
Given : Andrei's grandfather offered to give him a gift at 50% of the amount of money he saved in one year.
The amount saved by Andrei = $ 120
Then, the amount given by his grandfather to him will be
50% of ( amount saved by Andrei )
= (0.50) x ($120) [When we convert a percent into decimal we divide it by 100]
= $60
Therefore , the amount given by his grandfather to him = $60.
