Lobo is a leading manufacturer of positronic brains, a key component in robots. The company is considering two alternative production methods. The costs and lives associated with each are:

Year Method $1$ Method $2$

$0$ $ $6,700$ $ $9,900$

$1400620$

$2400620$

$3400620$

$4620$

Suppose all the costs are before taxes and the tax rate is $39\%.$ Both types of equipment would be depreciated at a CCA rate of $25\%($Class $9),$ and would have no value after the project. What are the EACs in this case $($r $=13\%)?$

a$.-$$$2,311\mathrm{.}65$ & $-$$$2,803\mathrm{.}42$ respectively, choose method $1$

b$.-$$$5,458\mathrm{.}16$ & $-$$$8,338\mathrm{.}7$ repectively, choose method $2$

c$.-$$$2,467\mathrm{.}65$ & $-$$$3,045\mathrm{.}22$ respectively, choose method $1$

d$.-$$$3,237\mathrm{.}6$ & $-3,948\mathrm{.}32$ respectively, choose method $1$

e$.-$$$3,081\mathrm{.}6$ & $-$$$3,706\mathrm{.}52$ respectively, choose method $1$
