Find the percent of change. Round to the nearest whole percent. Joe thought it would take him 74 minutes to complete the job. It actually took him 85 to complete the job.

15%

Step-by-step explanation:

plug your numbers to the equation

(85-74)/74 then multiply that by 100

then move the decimal right 2 places

14.8%

First of all, you need to find the difference between 85 min and 74 min.

85-74=11 min

Now, we need to find %increase-

increase/Original *100

11/74*100=

14.8648648649

= 14.8

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.
