Step-by-step explanation:
s = 8
1/2s = 4
add the 3 sides
8 + 8 + 4 = 20
Answer: 6.1% decrease
Note: It appears that your teacher doesn't want you to type in the percent sign, as that's already covered for you.
=========================================================
Explanation:
The salary decreased by 51500-48355 = 3145
Divide this over the initial salary to get 3145/51500 = 0.0611 which is approximate.
This converts to the percentage 6.11% and that rounds to 6.1%
----------------
As an alternative, you can use the formula method below
A = old value = 51500
B = new value = 48355
C = percent change when going from A to B
C = [ (B-A)/A ] * 100%
C = [ (48355-51500)/51500 ] * 100%
C = (-3145/51500)*100%
C = -0.0611*100%
C = -6.11%
C = -6.1%
The negative C value indicates a percent decrease.
Answer:
6-10b
Step-by-step explanation:
If we assume that when producing 190 bicycles vs 170 bicycles the difference in total daily cost is purely attributed to the extra 20 bicycles, THEN the cost to produce 20 bicycles (190 - 170) = 11600 - 10900 = 700
So the cost per bicycle is 700/20 = 35/bike
Now we can subtract the cost of bicycle production to determine the daily fixed cost that is not related to the number of bicycles.
i.e. 170 bicycles x 35 = 5950
So on a day that RideEm produces 170 bicycles, subtract 5950 from total day cost of 10900, which equals 4950.
So the fixed daily costs are $4950, and on top of this, the company pays 35/bike to produce.
