Given
The owner buys 144 pens for $28.80 i.e. each pen costs
owner sells the pen at $0.4 i.e. price marked up by
So, the claim of the owner is incorrect
The actual increase in the price to get 50% markup
So to write it out using order of operations it would be -7sinx+7sin^2x-(-7cos^2x). This would then equal 7-7sinx which can be simplified to 7(1-sinx). the way you were able to get rid of the cos^2x and the sin^2x is because cos^2x+sin^2x=1.
