Find the solution to:
Solve: 0.9x+9<_1.7x8

subtract 9
.9x<=1.7x17
divide by .9
x<= 1.7x/917/9
subtract 1.7x/9 from each side
x(11.7/9)<=17/9
x(1.19)<=17/9
divide both sides by .81 and you have it.
check my thinking. 
0.9X + 9 <= 1.7X  8.
0.9X  1.7X <= 8 9,
0.8X <= 17,
Divide both sides by 0.8 and reverse
inequality sign:
X >= 21.25.
