percent error=|\(\frac{predicted value-actual value}{predicted value}\)| times 100
(note the || is absolute value, means that whatever the result is inside, it is made positive)
predicted value=261
actual value=293
subsitute
percent error=|\(\frac{261-293}{261}\)| times 100
so using pemdas
do parenthasees first
|\(\frac{-32}{261}\)|
|-0.12|
absolute value
0.1226
time 100
0.1226 times 100=12.26
answer is 12.26%
answer is B
