To begin lets find next week's WPM. what is 15% of 25?
OpenStudy (anonymous):
idk
OpenStudy (anonymous):
well ten percent you would move the decimal to the left one spot
so 10% of 25.0=2.50
OpenStudy (anonymous):
what is half of 2.50
OpenStudy (anonymous):
1.25

yep
so add your 2.50 and 1.25 to find 15% of 25
OpenStudy (anonymous):
3.75
OpenStudy (anonymous):
cool, so add 3.75+25
OpenStudy (anonymous):
28.75
OpenStudy (anonymous):
and that will be his next weeks words per minute. you will have to do the same thing but instead of 15% of 25wpm, we use 15% of 28.75 wpm for the next week
