Emery Mining Inc. recently reported $147,500 of sales, $75,500 of operating costs other than depreciation, and $10,200 of deprec
Molodets [167]

Answer:

net income is $48452.81

Step-by-step explanation:

Sales =$147500

subtract operating expenses

-$75500 =$72000

subtract non- operating costs

depreciation -$10200 =$61800

-interest expense payable (16500*7,23%)$1196.25=63603.75

from profit before tax deduct income taxes =63603.75*25%=15150.9375

Net Income is therefore $63603.75-$15150.9375 = $48452.81

First, rewrite 14/25 and 11/20 so that they have a common denominator. Then, use <, =, >
muminat

Answer: 14/25 = 56/100

               11/20 =  55/100

               14/25 > 11/20

Step-by-step explanation:

The least common multiple of 20 and 25 is 100.

(100 = 20*5, 25*4)

So we can take the common denominator 100.

14*4/25*4 =56/100. ∴14/25 = 56/100

11*5/20*5  =55/100. ∴11/20  = 55/100

56>55

∴56/100 > 55/100

∴14/25 > 11/20

Hope it's good;)
