Yesterday morning Kathryn had 105 dollars. She first spent 1/3 of it at the mall. She counted her money. Later, she went to the movies and spent 5/7 of what was left after her shopping. How much money does she have now?

Answer: she has $20 left now.

Step-by-step explanation:

The total amount of money that Kathryn had yesterday was 105 dollars.

She first spent 1/3 of it at the mall. This means that the amount of money that she spent at the mall is

1/3 * 105 = $35

The amount left after her shopping would be 105 - 35 = $70

Later, she went to the movies and spent 5/7 of what was left after her shopping. This means that the amount of money that she spent at the movies is

5/7 * 70 = $50

The amount that she has left now is

70 - 50 = $20
