Question

find the weighted average of these values.
value weight
3.00 75.0%
4.00 15.0%
5.00 10.0%
weighted average:

Explanation:

Step1: Convert weights to decimals

$75.0\% = 0.75$, $15.0\%=0.15$, $10.0\% = 0.1$

Step2: Multiply each value by its weight

$3.00\times0.75 = 2.25$, $4.00\times0.15=0.6$, $5.00\times0.1 = 0.5$

Step3: Sum the products

$2.25 + 0.6+0.5=3.35$

Answer:

$3.35$
