Answer:
4.875 billion hours
Step-by-step explanation:
-Let X be the total time spent on taxes and 7.8 billion (80%) is time on paper work.
#We equate and cross multiply to get the total time on taxes:
-let y be the 50% amount of time spent. we equate to find it in actual hours:
Hence, 50% of the time is equivalent to 4.875 billion hours
Answer:
$2,844
Step-by-step explanation:
we know that Budgeted Production i = Estimated Sales + Closing Inventory - Opening Inventory
so budgeted production of may
= may sales + 40% of June Sales - 40% of May Sales)
=280+ ( 300*40%) - (280*40%)
=288 units
Budgeted Purchase in kg for May = Required for May's Prod + (30% Required for June Prod) - ( 30% of May Prod)
= 288*5 + ( 276*5*30%) - (288*5*30%) ( June production= 300+ 240*40% - 300*40%) = 276
=1.422 kg
Budgeted Cost for Purchase of Raw Material = 1422* 2 = $2,844

Answer: y = x^3+2x^2+3</h3>
========================================================
Explanation:
If you plug in x = 0 and y = 3, then the original equation boils down to c = 3. The x = 0 cancels out pretty much everything except that c term.
We have y=ax^3+bx^2+c update to y=ax^3+bx^2+3
Now plug in x = 1 and y = 6 from the point (1,6)
y=ax^3+bx^2+3
6=a(1)^3+b(1)^2+3
6 = a+b + 3
a+b = 6-3
a+b = 3
Now plug in the coordinates of (-1,4) which are x = -1 and y = 4
y=ax^3+bx^2+3
4=a(-1)^3+b(-1)^2+3
4 = -a + b + 3
-a+b = 4-3
-a+b = 1
-----------------------------
Here are the two equations we're interested in
a+b = 3
-a+b = 1
We'll add these equations straight down. The 'a' terms cancel. The b terms add to 2b. The right hand sides add to 3+1 = 4
We're left with 2b = 4 and it solves to b = 2
Use any of the equations involving 'a' and b to determine that a = 1
-----------------------------
To summarize we have
a = 1
b = 2
c = 3
This means y=ax^3+bx^2+c updates fully to y=1x^3+2x^2+3 which simplifies to y = x^3+2x^2+3 and it's the final answer.
