a shape with rotational symmetry can be rotated around a point so that all of its characteristics are maintained
kirza4 [7]

Please answer this multiple choice question correctly for 30 points and brainliest!!
marishachu [46]

Step-by-step answer:

Given:

Initial monthly salary = $5000

New salary = 10% less

Salary a year after = 15% more

Solution:

New salary

= 5000 * (100-10)%

= 5000 * 90%

= 5000 * 90/100

= 4500

Salary a year after

= 4500 * (100+15%)

= 4500 * 115%

= 4500 * 115/100

= 45*115

= 5175
