### Solve applied problems involving Definite Integrals

1. The marginal cost of a certain electronics firm is given by the equation

where C′ is in thousands of pesos and the quantity x produced is in hundreds of units per day. If the number of units produced in a given day changes from two hundred to five hundred units, what is the change in cost?

2. The marginal cost function for producing x units of ACU is **3×2 − 200x + 1500** pesos. Find the increase in cost if production is increased from 90 to 100 units.
