the four transactions above were on marcos bank account. what was the average transaction? a $12.06 b $30.94 c $12.40 d -$4.82
Answer
Explanation:
Step1: Calculate the sum of transactions
$$ \begin{align*} &- 19.25+14.75 - 18.50+71.25\ =&(-19.25 - 18.50)+(14.75+71.25)\ =&-37.75 + 86\ =&48.25 \end{align*} $$
Step2: Calculate the average
The average of (n = 4) numbers is (\frac{\text{Sum of numbers}}{n}). So the average is (\frac{48.25}{4}=12.0625\approx12.06)
Answer:
A. $12.06
