help please? What is supply curve if you know the total cost curve is TC(q) = 250q? I am confused on what to do

Assume that there are many, many rms that sell mobile phones, and assume that the rms' products are perfect substitutes, so that the supply of mobile phones can be characterized as perfect competition. Potential buyers are heterogenous in their valuation for mobile phones and each potential buyer consumes at most 1 mobile phone. Suppose that there are 1000 agents with a positive willingness to pay for a phone. These willingness to pays are uniformly distributed between 1 and 1000. Hence, someone has willingness to pay 1000, someone has willingness to pay 999, someone has willingness to pay 998,..., someone has willingness to pay 2, and someone has willingness to pay 1 for a mobilephone.. Assume that every rm's total cost curve is given by TC (q) = 250q, where q is the amount produced by the rm. Furthermore, assume that the rms have no xed costs. a) Draw the demand curve (approximately). b) Draw the market supply curve. C) Suppose now that the government imposes a 100 dollar tax on mobile phones. How much tax revenueas measured in dollarswill the government get in total? 01) How largeas measured in dollarsis the welfare loss from the tax in (c)
