How many percent is the change in the price, if: a The price was $75 and now it is $300?

300% increase

Step-by-step explanation:

We know this is an increase since the price goes up

Take the new price and subtract the original price

300-75 = 225

Divide this by the original price

225/75 = 3

Multiply this by 100% to get percent form

3*100%=300%

The percent change would be a 300% change

Step-by-step explanation:

$75 to $75 would have been a 0% change as there was no change

$75 to $150 would be an 100% change as you doubled the money amount

$75 to $225 would be an 200% change as you tripled the money

$75 to $300 would be a 300% change as you triple the amount of money
