If A = 50 and B = 75, what is the percent increase from A to B?

If A = 50 and B = 75, what is the percent increase from A to B?

• A. 50%
• B. 25%
• C. 100%
• D. 60%

Answer: (A)

To find how much something has increased in percent, use the formula: percent increase = (new value − original value) ÷ original value × 100%. Here, the increase from 50 to 75 is 25. So 25 ÷ 50 = 0.5, and 0.5 × 100% = 50%. That means the value increased by 50% from the original amount. If you check the other options, adding 25% would put you at 62.5, not 75; adding 60% would put you at 80; and 100% would double to 100. The 50% increase is the one that gets you from 50 to 75.
