The correct answer is:

She had $40 left.

Step-by-step explanation:

She had $75 to begin with. Giving 1/3 of it away means she gives away

1/3(75) = 1/3(75/1) = (1*75)/(3*1) = 75/3 = 25

After she gives way $25, she has

75-25 = $50 left.

Giving away 1/5 of this balance means she gives away

1/5(50) = 1/5(50/1) = (1*50)/(5*1) = 50/5 = 10

This gives her

50-10 = $40 left.

75 divided by 3 is 25, so she gave the first person 25. 75 divided by 5 is 13 for the second person. 13 + 25 is 38, and 75 - 38 is 37, so she had $37 left. Hope this helps!
