A merchant imported a batch of 80 porcelain vases for $4,800. Upon receiving the batch, he found 5 vases to be broken and threw them away. He sold 4/5 of the remaining vases at a profit of 40% and the rest at a loss of 10% on his cost price based on the 80 vases. Find his overall profit or loss as a percentage of his cost price based on the 80 vases.

the 3rd option is right

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
