NT Inc. makes each unit incurring variable costs of $$7$ for materials and $$3$ for labor. Another $$2$ is estimated to be the fixed cost burden on each unit. They then add a profit of $40\%$ on unit selling price. Assume that material and labor are the variable costs. Based on these details.

Each unit of the product generates $C of $$10$

$[$Each dollar of sales of the product generates contribution of $50$ cents$]$ and $[$Each unit of the product generates $$C$ of $$10]$ are both correct

All the other $4$ answers are correct.

Each dollar of sales of the product generates contribution of $50$ cents
