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? hurry and tell me!

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

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
