Lee buys his co-workers at the pharmacy doughnuts in the morning for $2 a doughnut.  he also makes an afternoon trip to the same bakery to purchase the same number of doughnuts to take home but the price has been reduced to $1 a doughnut. let x represent the number of doughnuts lee has purchased. write an expression that represents these purchases.

For this case, the first thing we must do is define a variable.
 We have then:
 x: the number of donuts Lee you have purchased
 In the morning we have:
 2x
 In the afternoon we have:
 x
 Therefore, the total amount that Lee buys is:
 2x + x
 
 an expression that represents these purchases is:
 2x + x

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
