Question

Last week, you finished Level 2 of a video game in 32 minutes. Today, you finished Level 2 in 28 minutes. What is your percent of change?

Answer 1

`color(indigo)("Percentage Change " P = 12.5% " reduction"`

Explanation:

`"Time taken to finish Level 1 " T_1 = 32 min`

`"Time taken to finish Level 2 " T_2 = 28 min`

`" Percentage change " P = ((T_2 - T_1) / T_1) * 100`

`=> ((28 - 32) / 32) * 100 = -(cancel4 * 100) / cancel(32)^color(red)(8)`

`=> -100 / 8 = - 12.5%`
