Today there are 3,431 thousand elementary and secondary teachers employed in a certain country. This number is expected to increase to 3,732 thousand teachers by the next decade. What is the percent​ increase?

Respuesta :

A = old value = 3431

B = new value = 3732

C = percent change

C = [ (B-A)/A ] * 100%

C =  [ (3732-3431)/3431 ] * 100%

C = (301/3431) * 100%

C = 0.0877 * 100%

C = 8.77%

Answer: Roughly an 8.77% increase

Note: if C was a negative value, then we'd have a percentage decrease
