Table is attached below
From the table we can see that the Lemon cost is equal to 35% of the expenses
Let the expense be x, Lemons cost is 70
Lemon cost = 35% * x
70 = 35% * x ( 35% = = 0.35)
70 = 0.35 * x
x =
x= 200, Expense = $200
Given : Profit percentage is 15%= = 0.15
Profit = profit percentage * Expense
Profit = 0.15 * 200 = 30
So profit = $30
Answer:
see the procedure
Step-by-step explanation:
we have
we know that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
In this problem
The domain for x is the interval [0,∞)
All real numbers greater than or equal to zero
The range for y is the interval (-∞,0]
All real numbers less than or equal to zero
The graph in the attached figure
therefore
On a coordinate plane, an absolute value curve opens down and to the right in quadrant 4 and starts at (0, 0)
