Answer:
$15.25
Step-by-step explanation:
Let's make x, the money raised by Anthony!
We know that Luis raised 3 times what Anthony did! That is 3x!
And because of Luis raised $45.75, we can say:
3x=45.75
Then to leave x alone we divide by 3 both sides of the equation!
And we get:
[tex]3x=45.75\\\frac{3x}{3}=\frac{45.75}{3} \\\\x=15.25[/tex]
So Anthony raised $15.25!
We verify that by multiplying 15.25 by 3 and we get 45.75!
