What is the formula for calculating percent increase or decrease?

The formula for calculating percent increase or decrease is [(final value - initial value) / initial value] x 100.

Calculate the percent increase if a value goes from 50 to 60.

To calculate the percent increase when a value goes from 50 to 60, subtract the original value from the new value to get the increase (60 - 50 = 10). Then, divide the increase by the original value (10/50 = 0.2). Finally, multiply the result by 100 to get the percentage increase, which is 20%.

Calculate the percent decrease if a value goes from 80 to 60.

To calculate the percent decrease when a value goes from 80 to 60, first find the difference between the two values: 80 - 60 = 20. Then, divide the difference by the original value (80) and multiply by 100 to get the percentage decrease: (20/80) * 100 = 25%. Therefore, there is a 25% decrease when the value goes from 80 to 60.

A shirt was originally $30 and is now $45. What is the percent increase?

The percent increase from $30 to $45 is 50%. This is calculated by taking the difference between the two amounts ($45 - $30 = $15) and then dividing it by the original amount ($15 / $30 = 0.5), which equals 0.5 or 50% when converted to a percentage.

The price of a phone decreased from $500 to $400. What is the percent decrease?

The percent decrease in the price of the phone is 20%, calculated by taking the difference between the original price ($500) and the new price ($400) which is $100, then dividing that by the original price ($500), and multiplying by 100 to get the percentage.

If a population increased from 1,000 to 1,200, what is the percent increase?

The population increased by 20% from 1,000 to 1,200. This can be calculated by finding the difference between the two populations (1,200 - 1,000 = 200), dividing that difference by the original population (200 / 1,000 = 0.2), and then converting that decimal to a percentage (0.2 x 100 = 20%).

If a stock price dropped from $50 to $45, what is the percent decrease?

The percent decrease in the stock price is 10%, calculated as the difference between the initial price of $50 and the final price of $45 divided by the initial price ($50 - $45) / $50 = 0.10 or 10%.

The sales of a product increased from 100 units to 150 units. What is the percent increase?

The percent increase in sales is 50%, calculated by taking the difference between the new and old values (150 - 100 = 50) and dividing it by the old value (50/100 = 0.5 or 50%).

If the temperature was 80°F and dropped to 70°F, what is the percent decrease?

The percent decrease in temperature from 80°F to 70°F is 12.5%. To calculate this, you would find the difference between the two temperatures (80-70 = 10), divide that difference by the original temperature (10/80 = 0.125), and then multiply by 100 to get the percentage (0.125 * 100 = 12.5%).

A company's revenue increased from $1 million to $1.5 million. What is the percent increase?

The percent increase in revenue is 50%. This is calculated by taking the difference between the new revenue ($1.5 million) and the old revenue ($1 million), which is $0.5 million. Then dividing this difference by the old revenue and multiplying by 100 to get the percentage increase: ($0.5 million / $1 million) x 100 = 50%.
