After a price increase of 20% the cost of entry to a museum rose to $25.80. Find the original entry fee

21.5

Explanation:

a x 120/100 = 25.8
a x 6/5 = 25.8
a = 25.8 x 5/6
a = 21.5

Where a is the original price.

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
