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

Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house. What was the total distanc
Makovka662 [10]

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

36 = \frac{48}{100}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

Last year , there were 30 male members and 20 female members in a Chess Club . This year , the number of male members is decreas
LekaFEV [45]

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

30\times\cfrac{r}{100} = 0.3 r

and similarly, the r% of female is

20\times\cfrac{r}{100} = 0.2 r

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

30 - 0.3r

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

20+0.2r

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

30 - 0.3r = 20+0.2r

Subtract 20 and add 0.3r from both sides:

10 = 0.5r

Divide both sides by 0.5 to solve for r:

r = 20

Let's check the answer

The 20% of 30 is 30 \times \frac{20}{100} = 6, while the 20% of 20 is 4. So, we are stating that 30-6 = 20+4 which is true because both expressions evaluate to 24.
