0.15x+55>0.10x+80 how do i work this out?

Answer 1

work it just like an equation, remembering to reverse the direction when multiplying/dividing by negative values:

0.15x+55>0.10x+80
0.15x - 0.10x = 80 - 55
0.05x = 25
x = 500

Answer 2

Oops. forgot it was not an equation:

0.15x+55>0.10x+80
0.15x - 0.10x > 80 - 55
0.05x > 25
x > 500
