I set Jon an equation and solved for number of hours
80 + 150 - 45= 185 (take away 45 as that was duplicated in the groups)
185/500= 0.37
The ratio is 5:39. We cannot simplify it, so the odds are 5:39.
0.08x+0.07 (3600-x)=264
Solve for x
0.08x+252-0.07x=264
0.08x-0.07x=264-252
0.01x=12
X=12÷0.01
X=1200 invested at 8%
3600-1200=2400 invested at 7%
The education is (x-h)^2 + k ands the vertex is (h,k)
