Answer:
$10278
Step-by-step explanation:
Given data
P= $6000
R= 8%
T= 7 years
The compound interest formula is
A=P(1+r)^t
substitute
A=6000(1+0.08)^7
A=6000(1.08)^7
A=6000*1.713
A=$10278

Define their age
---------------------------------------------------------------------------------------
Let Jim be x years old
Jim = x
Father = x + 31 ← Jim is 31 years younger than the father
Grandfather = x + 70 ← Grandfather is 70 years older than Jim
---------------------------------------------------------------------------------------
Combined age is 137, find x
---------------------------------------------------------------------------------------
x + (x + 31) + (x + 70) = 137
x + x + 31 + x + 70 = 137
3x + 101 = 137
3x = 137 - 101
3x = 36
x = 12
---------------------------------------------------------------------------------------
Find their age
---------------------------------------------------------------------------------------
Jim = x = 12
Father = x + 31
Father = 12 + 31
Father = 43
Grandfather = x + 70
Grandfather = 12 + 70
Grandfather = 82
---------------------------------------------------------------------------------------
Answer: Jim = 12 ; Father = 43 ; Grandfather = 82

Answer:
There was an 11% increase.
Step-by-step explanation:
The formula to find a percent increase is this: (original amount - new amount / original amount) * 100
If you fill in the formula, you get this:
(164,000 - 182,040 / 164,000) * 100
Solve:
(-18,040 / 164,000) * 100 ---> If the number being divided is negative, find the absolute value.
(18,040 / 164,000) * 100 =
0.11 * 100
11%
