Answer:
$1,109.80
Step-by-step explanation:
$3580 times 31% = 1,109.80+ 3580 = $4,689.80
The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
Answer:
It would be hundreds
Step-by-step explanation:
I hope it is right :I
