Option A: is the equation.
Explanation:
Let x represents the number of hours per month the store is open.
It is given that the the monthly rent(expense) = $1200
Also, the employee salary for each hour(expense) = $120x
Thus, the total expense C(x) is
It is also given that the income per hour(revenue) is $200x
Thus, the revenue function R(x) is
The break - even point is given by
Total expense = Revenue
Thus, is the equation.
Hence, Option A is the correct answer.

Answer:
The jeweler made 11 bracelets and 7 necklaces.
Step-by-step explanation:
Given that a jeweler had a fixed amount of gold to make bracelets and necklaces, and the amount of gold in each bracelet is 6 grams and the amount of gold in each necklace is 16 grams, knowing that the jeweler used 178 grams of gold and made 7 more necklaces than bracelets, to determine a system of equations that could be used to determine the number of bracelets made and the number of necklaces made, the following mathematical reasoning should be considered:
(16 - 6) x 7 = 70
178 - 70 = 108
108/6 = 18
18 - 7 = 11
(11 x 6) + (7 x 16) = X
66 + 112 = X
178 = X
Thus, the jeweler made 11 bracelets and 7 necklaces.
Answer:
c
Step-by-step explanation:
In the experimental design we are choosing a random rats from both sets either male and female.
each set contains 2 elements (A,B), where A is a Female i.e F1, F2,F3,F4
and B is a male i.e M1,M2,M3,M4.
none of the sets can have 2 male or 2 female.
Only option 'C' has sets which contains B (F3, F2) and D (M3, M4) which is impossible.
Hence c is the answer.
