A regional grocery chain measures the increase in prices by tracking the price of milk, eggs, white bread, and ground beef using the year 2005 as a base. The sum of these items in 2005 was $10.00 and the sum of the prices in 2015 was $14.50. What is the simple index for these items?

10.0

125

1.45

145

145

CORRECT: The simple composite index is calculated using the formula: Index = (Current Period Sum/Base Period Sum) x 100. Substituting the given values: (14.50/10.00) x 100 = 145. This means the prices of these grocery items have increased by 45% since 2005.
