How to solve? sarah has a $100 she gave 3/4 of the money to her sister. she gave a 1/2 of the rest of the money to her friend. how much money does she have left after giving the money away?

$12.50

Step-by-step explanation:

Sarah starts out with $100. She gave 3/4 of it away. 3/4 of 100 is 75. So, that means she gave $75 to her sister. she has $25 left but she gives half of the 25 to her friends. You would divide 25 by 2. since you have to split the 25 in half. she gave away $12.50 and she kept $12.50 for herself. So, she has $12.50 left after giving the money away.
