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](https://tex.z-dn.net/?f=%5Cdfrac%7B%5C%24120%7D%7B2%7D%20%3D%20%5C%2460)
You can also think of it this way:
![50\%=\dfrac{50}{100}](https://tex.z-dn.net/?f=50%5C%25%3D%5Cdfrac%7B50%7D%7B100%7D)
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](https://tex.z-dn.net/?f=%5C%24120%5Ctimes%5Cdfrac%7B50%7D%7B100%7D%20%3D%20%5Cdfrac%7B%5C%246000%7D%7B100%7D%3D%5C%2460.00)
Answer:
$48
Step-by-step explanation:
To start off, we know that Avery put 20% of the $80 in her bank account. We can figure out how much 20% of 80 is by multiplying 80 by 20% and then subtracting that number from 80. Remember to switch 20% to its decimal form (20% -> .2).
Step 1) 80 x .2 = 16
Step 2) 80 - 16 = 64
Next, we have to figure out how much 1/4 of the remaining $64 would be. We just simply divide 64 by 4 to figure out how much Avery spent.
Step 3) 64 / 4 = 16
Lastly, since we know Avery spent 16 dollars, we can subtract the 16 from 64 to get our final answer.
Step 4) 64 - 16 = 48
