Inverse variation means y=k/x (direct variation is y=kx)
You are given a point, so you can solve for the constant k...
2=k/15
k=30 so the function is:
y=30/x
The system of equations is
3d+7p=61.25
12d+9p=107.25
Ok so Jesse is 10-15%
Margie is <10%
Pietro is >15%
Susana is 10%-15%
And I think Raul maybe >15%
Basically you can determine how far off they are by doing the number they guessed divided by the actual number (132) so for Jesse I did 120/132 and I got .909 and so on. Just take the two numbers after the decimal and that’s your percent. So the .909 is about 90% so now do 100% (of the 132) - 90 and you get 10. So I put 10%-15%
