need help, I think I did first part correct but stuck on second part

3. Emissions Taxes and Cost-Effectiveness -1 2 among'llanimamung I bonoge S Consider the same two polluting firms. "Firm I's marginal abatement cost is given by MC, = 700 + e,, where e, is the tons of pollution abatement by Firm 1. Firm 2's marginal abatement cost is given by 19 MC2 = 2ez, where ez is the tons of pollution abatement by Fin 2. Both marginal abatement costs are in dollars per ton. Each firm's baseline pollution level is 1500 tons, for a total baseline pollution level of Ri 3000 tons.end fulor a 101 980 00) ar lool notmullog smilaand amit road nal dog.hallab mista ergdo aroy OQUE to fovol nohullon Suppose that the government imposes a tax of $1,000/ton of pollution.
