s	2,000,200	29,200	68.5
t	3,408,000	71,000	48.0
u	8,838,636	214,530	412.0

an error was made in calculating the bushels harvested per acre for 1 county. which county contains the error?
a. county q
b. county r
c. county s
d. county t
e. county u

Explanation:

Step1: Recall the formula for bushels per acre

Bushels per acre = $\frac{\text{Amount harvested (bushels)}}{\text{Area planted (acres)}}$

Step2: Calculate for County U

$\frac{8838636}{214530}=41.2$ not $412.0$
So the error is in County U.

Answer:

E. County U
