Answer:
18,000 units .
Step-by-step explanation:
The cost function C(x) and the revenue function R(x) are, respectively:
In order to break even, the revenue function, for a given value of "x" must yield a value equal or greater than the cost function. Simply equal both functions to find a minimum value of x needed to break even:
18,000 units must be sold in order to break even.

Answer:
5 per noun, 8 per verb
Step-by-step explanation:
start by defining what each variable is
v = n+3
v = 2n-2
substitute v for one of the equations above
n+3 = 2n-2
subtract n from both sides
3 = n-2
add 2 to each side
5 = n
so there are 5 flashcards per noun
substitute 5 in for n in both equations
v = 5+3
and
v = 2(5)-2
solve both equations
v = 8 and v = 8
so there are 8 flashcards per verb
-22 is the answer because since 2 is negative and 11 is positive the answer is going to be negative. Hope it helps
