Answer:
Break even occurs at 2800 juice boxes.
Explanation:
Fixed cost form the factor = $1400
Variable cost per unit juice box = 15 cents = $0.15
Let number of juice boxed produced to get brek even point = x
Then total cost = c(x)= 1400+0.15x
Selling price per unit juice box = 65 cents = $0.65
Then total sales = R(x)= 0.65x
At break even both sales and cost will be equal so we get:





Hence break even occurs at 2800 juice boxes.
