Answer the following question, with explanation first.
Maria gave a third of her money to her friend Isha, half of what she gave to Florence. If Florence received three times as much money as Maria's cousin Rene, and Rene received $300, how much money did Maria give her three friends?

1650
The total amount of money that Florence received is 3 * 300 = $900, three times as much money as Rene received.

Maria gave Isha half the amount of money that Florence received, which is $900 / 2 = $450.

Maria gave her friends $450 + $900 + $300 = $1650.

.

The final answer: 1650
