Answer:

$20

Step-by-step explanation:

First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

[tex]4:3 \rightarrow 4:(3+4)=4:7[/tex]

Now we can solve for how much money Siti receives using a proportion.

[tex]\frac{4}{7} = \frac{\mbox{money Siti receives}}{35}[/tex]

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.
