Unit cost of the first item . . . . p
Number of these ordered . . . n
Cost of these . . . . . . . . . . . . . . . np
Unit cost of the second item . . . (p + 9)
Number of these ordered . . . . . 2n
Cost of these . . . . . . . . . . . . . . . . 2n(p + 9)
Cost of the total order . . .
np + 2n(p + 9) =
np + 2np + 18n =
n (p + 2p + 18) =
n (3p + 18) = 3n (p + 6)

Remove parentheses and simplify 7X-4X-9?
As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
