We have to add 1 in numerator and -10 in denominator because
![\tt \frac{8}{101} , \frac{9}{91} , \frac{10}{81} , \frac{11}{71} ...[Given]](https://tex.z-dn.net/?f=%20%5Ctt%20%5Cfrac%7B8%7D%7B101%7D%20%2C%20%5Cfrac%7B9%7D%7B91%7D%20%2C%20%5Cfrac%7B10%7D%7B81%7D%20%2C%20%5Cfrac%7B11%7D%7B71%7D%20...%5BGiven%5D)

The difference is 1 in numerator so we add 1 and the difference is -10 in denominator so we subtract -10.
16 squared is 256 because if you multiply 16 times 16 you get 256
(new - original)/original = mark up
(78.08-64)/64= mark up
14.08/64 =mark up
.22 = mark up
multiply by 100 to get to a percent
mark up = 22 percent
21x+14u-28would be the answer.
