The marginal cost is how much it costs to produce one item more. It cost 0$ to produce 0 bikes but if you make one, then it costs 80$. Hence the marginal cost for the first bike is 80$. For the fourth bike, we have that the 3 bikes cost 110$ and the 4 bikes cost 130$. Hence it costs 20$ dollars to produce one more bike (from 3rd to 4th) and hence the marginal cost is 20$. Similarly for the 6th bike, we compare the cost of producing 5 bikes to the cost of producing 6 bikes and we get that the marginal cost is 50$. Applying the same methodology, the marginal cost for the 7th bike is 60$.

Answer:
4 years
Explanation:
Let x be the age ( in years ) of each daughters,
∵ Mother is 30 years older than her daughters,
⇒ Age of the mother = x + 30
Now, after 2 years,
The age of each daughter = x + 2,
And, the age of the mother = x + 30 + 2 = ( x + 32 ) years,
According to the question,
3(x+2+x+2) = x + 32
3(2x+4) = x + 32
6x + 12 = x + 32
5x = 20
⇒ x = 4
Hence, each of the daughters is 4 years old.
