a$.$ What would be the effect on OneCo's operating income if it accepts the proposal from Zelda, but rejects the proposal from Gatsby?

b$.$ What would be the effect on OneCo's operating income if it accepts both proposals?

c$.$ Assume Gatsby has offered a second proposal to purchase $2,000$ units at the market price of $$16\mathrm{.}50,$ but has requested product modifications that would increase materials cost by $$0\mathrm{.}30$ per unit and increase direct labor and variable overhead by $15\%.$ The sales commission would be $$0\mathrm{.}35$ per unit. Should OneCo accept this order? Why or why not?

d$.$ Assume OneCo had excess capacity. What would be the effect on OneCo's operating income if it accepts the Gatsby proposal described in c$.?$ Assume no additional fixed costs would be generated.
