In 2017 john paid$10.00 to watch a movie at the theater. in 2019 john paid $12.00 to watch a movie at the theater. what is the percent increase?

show me how it is figured out

20% increase

Step-by-step explanation:

percent increase formula :

percent increase= [(new value-original value)/original value] * 100

                            = [(12-10)/10] * 100

                            = [2/10] * 100

                            = 0.2 * 100

                            = 20%

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
