Let x be the amount invested at 7% and y the amount invested at 6%
We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500
5 ft = 5 * 12 in = 60 inches
Four consecutive even numbers are: x, x + 2, x + 4, x + 6
x + x + 2 + x + 4 + x + 6 = 60
4 x + 12 = 60
4 x = 60 - 12
4 x = 48
x = 48 : 4
x = 12
Answer:
Those shelves should be: 12, 14, 16 and 18 inches long.
Verification: 12 + 14 + 16 + 18 = 60 in = 5 ft.

Answer:
the answer is 2.4 million
Step-by-step explanation:
In order to find the rate of change, you first must find the amount that the population grew in the time period:
314-302 = 12
Now you need to calculate the number of years:
2012-2007 = 5
Lastly, divide the amount of change by the number of years:
12/5 = 2.4
The population grew by 2.4 million people per year. Hope this helps! :)
