Answer:
N$12 576. 11
Step-by-step explanation:
Loss%=10%
S.P= N$11 480.50
C.P =?
Loss%=100(C.P - S.P)/C.P
10=100(C.P-11 480.50)/C.P
10C.P=100C.P - 1 148 050
1 148 050=100C.P - 10C.P
1 148 050=90C.P
C.P=N$12 576.11
Answer:
Option D is correct.
75 miles is the total distance in miles to Kirk's grandmother's house
Step-by-step explanation:
Let x represents the total distance in miles to Kirk's grandmother's house.
As per the statement:
Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house
⇒ Distance Kirk's family drove = 36 miles.
then;
36 = 48% of x

Multiply both sides by 100 we get;
3600 = 48x
Divide both sides by 48 we have;
75 miles = x
Therefore, the total distance in miles to Kirk's grandmother's house is 75 miles
The r% of a quantity x is computed by dividing x in 100 parts, and considering r of such parts. So, the r% of the male is

and similarly, the r% of female is

The number of males decreased by this quantity, so now it is

and the number of female increased by this quantity, so now it is

we know that these two new counts are the same number, so we can build and solve the equality

Subtract 20 and add 0.3r from both sides:

Divide both sides by 0.5 to solve for r:

Let's check the answer
The 20% of 30 is
, while the 20% of 20 is 4. So, we are stating that
which is true because both expressions evaluate to 24.
