Question

Answer 1

Answer:

Third week, 15 words per minute

Step-by-step 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
