Question 1141468

For selling an item for N850 a trader made a profit of 15%. What should be selling price be to make a profit of 20%?
<pre>Making a profit of 15% means that itw's sold for 1 + .15, or 1.15
Making a profit of 20% means that it should be sold for 1.2
We therefore get the simple PROPORTION: {{{highlight_green(matrix(1,3, 1.15/1.2, "=", 850/S))}}}, with S being the selling price to make a 20% profit
Solve that for S to get your answer! 
Cross-multiplying or multiplying both sides by LCD, 1.2S should get you there.
