You can put this solution on YOUR website!
a%2Asqrt%2810000%29%2Bb=20
1.100a%2Bb=20

,
,
a%2Asqrt%2862500%29%2Bb=35
2.250a%2Bb=35
Subtract 1 from 2,
250a%2Bb-100a-b=35-20
150a=15
Solve for a, then use either equation to solve for b.
Once you know a and b, then solve for,
P=a%2Asqrt%2840000%29%2Bb
That's your final answer.
