CORRECT ANSWER GETS A BRAINLIEST

Answer 1

Answer:

B.   N(c)  = (c-20)/n  

Step-by-step explanation:

Given

C(n) = 10n+20

we have to find the inverse of this function

we have to express n in terms of C(n)

C(n) = 10n+20

we have make n independent of n and remove any other term containing on the side of n

subtracting 20 from LHS and RHS

C(n) - 20 = 10n+20 - 20

C(n) - 20 = 10n

dividing LHS and RHS by 10

C(n)/10 - 20/10 = 10n/10

=> n = (C(n) - 20)/10

Now given in problem, N(c) is no of bushels picked

and c is the cost of apple

so in function n = C(n) - 20/10

we replace C(n) with c

and n with  N(c)  

and then we have

N(c)  = (c-20)/n   Answer
