Scottie believed Apple Co$.($AAPL$)$ stock was overpriced at the

price of $$115.$ She shorted $50$ shares. The brokerage firm required

an initial margin of $55\%$ and maintenance margin of $30\%.$ The price,

however, has been moving against Scottie$$s belief. If AAPL price

increases from $$115$ to $$127,$ how much would Scottie have to deposit

in her margin account?$$$$137\mathrm{.}12$$$0,$ because the price hasn't reached the threshold

yet.$$$$137\mathrm{.}12$ times $15$$$(127-115)$ times $50$
