Question

Jorge started the month with a balance of $400 in his checking account and ended the month with $450 what is the percent of the increase or decrease

Answer 1

Answer:

%12.5

Step-by-step explanation:

Step 1:  Make an equation

400x = 450

Step 2:  Divide both sides by 400

400x / 400 = 450 / 400

x = 1.125

Step 3:  Convert into a percentage

1.125 * 100

%112.5

The increase is %12.5

Answer:  %12.5

Answer 2

This questions shows a percent increase.

Formula: (new value - old value) ÷ old value * 100%

= (450 - 400) ÷ 400 * 100%

= 50 ÷ 400 * 100%

= 0.125 * 100%

= 12.5% increase.

Best of Luck!
