Avery is learning how to type. She increases the number of words she can type in a minute by 15% every week. This week she can type 25 words a minute. In 6 weeks how many words a minute should she be able to type?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

week one 25 wpm, week two 28.75 wpm, week three is 28.75 +15% increase

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

33.1 again

OpenStudy (anonymous):

15% of 28.75?

OpenStudy (anonymous):

dont i add 28.75 plus 3.75

OpenStudy (anonymous):

what did you get for 15% of 28.75

OpenStudy (anonymous):

i added 28.75 plus 3.75 and got 32.5

OpenStudy (anonymous):

you should add 28.75+4.3125 (15% of 28.75)

OpenStudy (anonymous):
