Answer:
$12,921.09
Step-by-step explanation:
1. 9,000*1.041(added 4.1 percent to whole debt)=$9369
2. 9,369*1.041=9,753.13
3. 9,753.13*1.041=10,153.01
4. 10,153.01*1.041=10,569.28
5. 10,569.28*1.041=11,002.62
6. 11,002.62*1.041=11,453.73
7. 11,453.73*1.041=11,923.33
8. 11,923.33*1.041=12,412.19
9. 12,412.19*1.041=12,921.09
$<u>12,921.09</u>
see the attached figure , to better understand the problem
we have
where
A(b) ---> is the trapezoid's area
b ---> is the other base value
Solve the equation for b
That means ----> isolate the variable b
Divide 12 by 2 right side
Divide by 6 both sides
subtract 9 both sides
Rewrite
Convert to function notation
nah man... good luck tho
