Answer:
64r -48r -144
Step-by-step explanation:
The January cost expression is ...
62p -48p -144 -432 = profit
The cost is identified as having 3 components, so the profit will have 4 components:
(selling price)×p - ((cost per unit)×p +(fixed monthly cost)) -(first month startup cost) = profit
Comparing this to the given equation, we identify the components as ...
selling price = 62
cost per unit = 48
fixed monthly cost = 144
first month startup cost = 432
We note that 432 = 3×144, so is consistent with the description of startup costs.
Increasing the selling price by $2 will raise it from 62 to 64. In February, the initial month startup cost disappears, so the profit equation becomes ...
(selling price)×r - ((cost per unit)×r +(fixed monthly cost)) = profit
64r -48r -144 = profit
Solving 
we get 
Option A is correct.
Step-by-step explanation:
We need to find the result of
We need to remove i from the denominator. For removing i Multiplying and dividing by 2-3i:
Solving:
So, solving we get
Option A is correct.

First add the 2 numbers in the ratio:
3+2 = 5
divide the 735 by 5:
735 / 5 = 147
now multiply 147 by 3 and then by 2 and that will be the ratios:
147 * 3 = 441
147 * 2 = 294
