Answer:

The answer is 22% decrease. (option A)

Step-by-step explanation:

Given that,

2015 population = 2.5 million

2000 population = 2 million

Let GDP (gross domestic product) for the year 2015 = X

then, GDP for the year 2000 = 5/8 X (i.e 3/8 less than that of 2015)

and the per capita GDP for 2015 = 2500000 / X

Also, the per capita GDP for 2000 = 2000000 / (5X /8)

= 3200000 / X

Comparing the per capita GDP of 2015 to that of 2000, there is a decrease from 2000 to 2015.

decrease = year 2000 per capita GDP - year 2015 per capita GDP

= 3200000 / X - 2000000 / X

= 700000 / X

The percentage decrease can be calculated as

percentage decrease = decrease *100 / year 2000 per capita GDP

= (700000 / X) *100 / (3200000/X)

= 21.875

= 22% decrease

The total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.The cost of each cookie is $0.95.Select the equation and its s

lisabon 2012 [21]

The equation for the situation is $5x+6(0.95)=11.95$

The solution to the equation is $x=1.25$

First, you must set up the equation.

$5x+6(0.95)=11.95$

Then, you must simplify the terms.

$5x+5.7=11.95$

Next, subtract 5.7 on both sides.

$5x=6.25$

Finally, divide 5 on both sides

$x=1.25$

A population of endangered birds decreases by 3% each year.

Lana71 [14]

Since the number of bird decreases 3% per year then for year 1 there will be 29 100 birds left. This value is 97% of 30000. From this the number of birds for year 1 is N = 30000(1-0.03)

A. N = 30,000 $(1-0.03)^{2}$

B. To solve this we use the equation we established in letter A. We get the answer by substituting T with 20. N = 16,000. <span />

LekaFEV [45]

Answer:

£116.67

Step-by-step explanation:

Given;

Nar donated to 4 charities last year. She gave £175 to each of these charities.

The total amount Nar donated is;

Nar = 4 × £175 = £700

For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;

A = £700/6

A = £116.67
