You'll calculate the amount it was decreased by :
15% is also 15/100
15/100 * 42000
The two 0's in 100 cut 2 of the 0's in 42000 making it :
15/1 * 420
15* 420 = 6300
So, 6300 is the amount that the price is decreased by, but the question says the price of the PC (personal computer) after the decrease has happened not the price it decreased by :
So,
42000 - 6300 = 35700.

Answer:
c. $20.23
Step-by-step explanation:
The overhead cost per labor hour is found by dividing overhead costs by labor hours:
$163,900/(8100 h) = $20.23 /h
The factory overhead rate is $20.23 per labor hour.
First setup the system of equations for the given case.
Let sandwich=x
and delivery fee =y
Equations are:
4x+y=33 Equation 1
8x+y=61 Equation 2
Subtract equation 1 from 2.
4x=28
x=7
Now substitute value of x in equation 1.
4(7)+y=33
28+y=33
y=5
So cost of single sandwich=$7 and Delivery fee=$5
Now cost of 12 sandwiches:
12x+y=85
Put y=5
12x+5=85
12x=80
x=6.67 which is less than 7. So, They are not able to get 12 sandwiches for $85.
Answer:
2x-7
Step-by-step explanation:
Answer:
That is 6 divided by 3/8, better written as
6

8
Invert the 3/8 and then multiply:
6 8
-- * ---
1 3
Reduce 6/3: 6/3 = 2
Then you have 2(8), or 16 (answer)
