B) $288.53
C) $293.47
D) $289.70

Answer 1

The 3-day Simple Moving Average (SMA) of the last three days of the given 10-day consecutive closing prices for Sherwin-Williams Co is $290.42, which is not one of the provided options.

Step-by-step explanation:

To determine the 3-day Simple Moving Average (SMA) for Sherwin-Williams Co for the last three days of the given 10-day consecutive closing prices ($242.50, $273.98, $278.16, $293.94, $285.04, $290.80, $296.02, $291.01, $293.41, $286.85), you would take the sum of the closing prices for days 8, 9, and 10 and divide by 3.

Let's calculate it:

• Day 8: $291.01
• Day 9: $293.41
• Day 10: $286.85

SMA = (Day 8 + Day 9 + Day 10) / 3

SMA = ($291.01 + $293.41 + $286.85) / 3

SMA = $871.27 / 3

SMA = $290.42

Thus, the correct answer is none of the provided options (A) $280.22, (B) $288.53, (C) $293.47, or (D) $289.70), as the accurate 3-day SMA is $290.42.
