To determine the value of n (the number of croissants baked and sold) that yields a 200% profit, we need to calculate the total revenue, total cost, and then ensure the profit matches the given condition.

First, we calculate the total revenue:

Each croissant is sold for 1.5 euros.
The total revenue for n croissants is 1.5n euros.

Next, we calculate the total cost:
The cost for the first 100 croissants is = 0.60×100=60 euros.

The cost for the additional
n−100 croissants is 0.30×(n−100) euros.
Total cost = 60+0.30(n−100)

Next, we determine the profit:
Profit is defined as revenue minus cost.
The given profit is 200%, which means the profit is 200% of the cost (or 2 times the cost).

Therefore: Profit=Revenue−Cost
=> Profit=1.5n−(60+0.30(n−100))

Simplifying the cost expression:
60+0.30(n−100)=60+0.30n−30=30+0.30n

Now, substitute this back into the profit equation:
Profit=1.5n−(30+0.30n)=1.5n−30−0.30n=1.2n−30

Given that the profit is 200% of the cost:
=> Profit=2×Cost
=> 1.2n−30=2×(30+0.30n)

Simplify the right-hand side:
=> 1.2n−30=2×30+2×0.30n
=> 1.2n−30=60+0.60n

Solve for n:
1.2n−0.60n=60+30
0.60n =90
n= 0.60*90 =150
Thus, the value of n is 150

Answer: B
