Answer:
B When the sales are 12, the profit is 400.
Step-by-step explanation:
Given
Required
Interpret the intersection
From the intersection, we have the following parameters.
Literally, it means
when
From the question, we understand that
s represents sales while p, profit.
So, the interpretation of is when sales = 12, profit = 400
The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅

y=3/4−x/4 is the answer if I'm not incorrect
