Answer:
Nina would have total expenses and sales $156 after selling 4 necklaces.
Step-by-step explanation:
Let <em>x</em> represent the amount of necklaces made and sold.
The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:

Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:

To break even, the total cost and profit must be equivalent. Hence:

Solve for <em>x: </em>
<em />
<em />
<em />
Hence, the break even, Nina would need to sell four necklaces.
And the total expenses/profit would be:

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.

Answer: 1/12
Answer:
I suppose that you want to find which gym will be cheaper for you.
We have two equations:
• Gym A: 30m + 50
• Gym B: 10m + 100
First, let's find the value of m such that both gyms cost exactly the same:
30*m + 50 = 10*m + 100
Let's solve this for m
30*m - 10*m = 100 - 50
20*m = 50
m = 50/20 = 2.5
now:
for m < 2.5, Gym A will be cheaper, because the y-intercept is smaller.
for m > 2.5, Gym B will be cheaper, because the slope is smaller,
Then depending on the number of months that Martin wants to go to the gym, he can se the info above to pick the one that is cheaper.
