can you help me :

a company must acquire a new automatic sorting system for its

L$$vis warehouse.

She has the option to purchase the device. Its cost of $$250,000$ will be financed by the

bank at an interest rate of $12\%.$ The loan must be repaid in six installments

equal, payable at the end of each year.

If the company opts for the purchase financed by loan it will have to maintain the device at

annual cost of $$12,000,$ payable at the end of the year.

It can also enter into a rental contract, requiring annual payments of

$$60,000,$ due at the beginning of each year. The maintenance will then be carried out by the

landlord.

The trolley belongs to category $10,$ to which a CCA rate of $30\%$ applies;

it is estimated that, after $6$ years, its market value will reach $$25,000.$

Whether it chooses to purchase or rent, Amaze Inc intends to replace

the cart after $6$ years. Its marginal tax rate is $40\%$ and its TRAM,

$15\%.$
