Can I get help with this question please

Solve for the Bertrand equilibrium for the firms described below if Firm 1's marginal cost is $15 per unit and Firm 2's marginal cost is $25 per unit. Firm 1 faces a demand function of 91 = 140 - 2p, + 1P2. where q, is Firm 1's output, p, is Firm 1's price, and p2 is Firm 2's price. Similarly, the demand Firm 2 faces is 92 = 140 -2p2 + 1P1- Solve for the Bertrand equilibrium. In equilibrium, p, equals and p2 equals . (Enter numeric responses using integers.)
