A firm prints advertising posters. They have a set-up fee of £100 and charge 8p per poster. Explain in words how to find the total cost of printing 250 posters. Hence explain why the total cost £(C)ofprinting N posters is given by the formula C = 100 + 0.08N. (b) Use the formula in part (ii)(a) to calculate the cost of printing 500 posters. (c) Rearrange the formula in part (ii)(a) to make N the subject of the equation. Explain carefully the steps in your working. (d) Use the result of part (ii)(c) to determine how many posters you can print for £200. (e) Another printing firm has a set-up fee of £50 and charges 16p per poster. Find a formula (similar to the one in part (ii)(a)) for P, the total price in £ when N posters are printed. (f) Solve the equation 100 + 0.08N =50 + 0.16N. Explain why the solution of this equation gives the number of posters for which the cost of printing is the same for both firms. thank you Dave Sorry this is how it should read…

If the net credit sales is 2,000,000.00 then what is the estimated bad debt expense for the next year. Please show the calculation.
