To find out her income in the first week, add $125 to 10% of 800.

125+(800*.1)=205

In the first week, she earned $205.

For the second week, you're trying to find out how much in books she sold. To find the value of the books she sold, subtract 125 from 225 and divide by 10%.

225-125=100
100/.1=1000

She sold $1000 worth of books in the second week

a) $205( for this you have to multiply the value of the first week by 0.1 or 10% to get 80 which you then add to her salary which is $125)  

b)$1000 ( for this you subtract the salary from the second week from the total which you multiply by 10 to get the total value of the books she sold)
