The population of a country was increased in the past 4 years. The annual presentage increases are 20%,25%,30%,10% respectively.

Vladimir79 [104]

The answer is 114.5%.

Let the original population be denoted by x.

Now, let's go through the percentage increase per year.

Year 1

x (1 + 20%)
x (1.2)
1.2x

Year 2

1.2x (1 + 25%)
1.2x (1.25)
1.5x

Year 3

1.5x (1 + 30%)
1.5x (1.3)
1.95x

Year 4

1.95x (1 + 10%)
1.95x (1.1)
2.145x

Overall increase : 214.5% - 100% = 114.5%

Hence, the overall percentage increase in these 4 years is 114.5%.

What is the solution to this equation? 4(4x + 1) = 3x - 46 - x) + 8

liubo4ka [24]

Answer:

4(4x+1)=(3x-46-x)+8

16x+4=3x-46-x+8

16x-3x+x=-46-4+8

14x=-42

14x/14=-42/14

x=-3
