We have:
f: <span>the amount of money that Frank spent.
r = the amount of money that Rachel spent.
</span>
The system of equations that represents this situation is:
1) f+r=15.75
2)r=2f
Let's substitute r=2f into the equation 1):
f+r=15.75
f+2f=15.75
3f=15.75
f=15.75/3
f=5.25
Now, we must substitute f=5.25 into the second equation, as it shows below:
r=2f
r=2x5.25
r=10.50
