Bezzdna [24]
Both Maria and Edwin are correct

Maria's method
25% of 26.50 = 6.625
26.50 - 6.625 = 19.875
10% of 19.875 = 1.9875
19.875 + 1.9875 = 21.8625 as final price

Edwin's method
75% of 26.50 = 19.875
110% of 19.875 = 21.8625 as final price

The book is 25% off the original price, so the remaining value is 75% of the original value
By adding 10% tax on to the original price, the final price will be 100%+10%=110% of the original price

Both Edwin and Maria has enough money to purchase the book
