Question

The first week Samantha learned to read Braille, she could read 10 words per minute. In the second week she increased her speed by 20%. In the third week she increased her speed again by another 25%. How many words could she read per minute by the third week? PLEASE HURRY AND TELL ME!

Answer 1

Third week, 15 words per minute

Explanation:

First week: 10 words per minute

Second week

10 * 20% = 10*.2 = 2

It is an increase, so we add the 2 to the original amount

10+2 = 12 word per minute

Third week

12 * 25% = 12 *.25 = 3

It was an increase, so we add the 3 to the amount in week 2

12+3 = 15 words per minute
