Answer:
The bottom left
Step-by-step explanation:
T = Total income
N = Number of purses
35N = the selling price of each purse
17N = Cost of each purse
T = 35*N - 17*N - 75
T = 18N - 75
If she wants here total income to be 350 dollars, it will take
T = 350 ; N = unknown.
350 = 18N - 75 Add 75 to both sides.
350 + 75 = 18N
425 = 18N
Rounded N = 24 <<<< Answer. The actually number is 23.611 but you can't sell 0.611 of a purse.

Answer:
c. f(x) x+1/x-1
Step-by-step explanation:
To answer this question, we need to check each answer one by one until we find the right one.
y = (x+6)/(x-6)
switch x and y
x = (y+6)/(y-6)
solve for y
x(y-6) = y+6
xy - 6x = y+6
y(x-1) = 6x+6
y = (6x+6) /(x-1) = 6(x+1)/(x-1)
f^-1(x) = 6(x+1)/(x-1)
y = (x+2)/(x-2)
switch x and y
x = (y+2)/(y-2)
solve for y
x(y-2) = y+2
xy -2x = y+2
y(x-1) = 2x+2
y = (2x+2)/(x-1)
f^-1(x) = 2(x+1)/(x-1)
y = (x+1)/(x-1) ------ correct one
switch x and y
x = (y+1)/(y-1)
solve for y
x(y-1) = y+1
xy - x = y+1
y(x-1) = x+1
y = (x+1)/(x-1)
f^-1(x) = (x+1)/(x-1)
f(x) = f^-1(x)
