Ineed on finding percent of change

ANSWER:

50% increase

The percent of change of 30 increased to 45 is a 50% increase.

STEP-BY-STEP EXPLANATION:

% of change = [ ( New amount - original amount ) / original amount ] × 100%

Let % of change = x

x = [ ( 45 - 30 ) / 30 ] × 100%

x = ( 15 / 30 ) × 100%

x = ( 1 / 2 ) × 100%

x = 0.5 × 100%

x = 50%
