Emily purchased lemons for $600. she sold 3/4 of these at a loss of 20% and the remaining at a gain of 20%. how much percent does she gain or lose in the whole transaction?

10%

Step-by-step explanation:

Given: CP of lemon is $600.

           3/4 of lemon sold at 20% loss

           Remaining lemon at 20% gain.

Considering the quantity of lemon remain constant.

Cost price of 3/4 of lemon=

As given, 3/4 of lemon sold at 20% loss.

∴ Selling price of

Selling price=

Hence, selling price of 3/4 lemon is $360.

Now, the cost price of remaining lemon

∴ The cost price of

As given, remaining

∴ Selling price of

Selling price of

Hence, selling price of 1/4 lemon is $180

Loss\profit percent=

∴ Loss\profit percent=

Hence, the loss percentage is 10%

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
