Answer:
%12.5
Step-by-step explanation:
<em>Step 1: Make an equation</em>
<em>400x = 450</em>
<u>Step 2: Divide both sides by 400</u>
400x / 400 = 450 / 400
<em>x = 1.125</em>
<u>Step 3: Convert into a percentage</u>
1.125 * 100
<em>%112.5</em>
<em>The increase is %12.5</em>
Answer: %12.5
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!
