A package 8 of -count AA batteries 6.40 costs . A package of 20-count AA batteries 15.80 costs . Which statement about the unit prices is true?
unit cost of first set = 6.4/8 = .80
unit cost of 2nd set = 15.8/20 = .79
You decide which statement is true, since we don't see any statements
To determine which statement about the unit prices is true, we need to compare the prices of the two packages and calculate the unit prices for both.
Let's start by finding the unit price for the package of 8-count AA batteries. We can do this by dividing the total cost of the package by the number of batteries in the package:
Unit price for 8-count package = cost of package ÷ number of batteries
Unit price for 8-count package = 6.40 ÷ 8
Using a calculator, we find that the unit price for the 8-count package is 0.80.
Now let's calculate the unit price for the package of 20-count AA batteries:
Unit price for 20-count package = cost of package ÷ number of batteries
Unit price for 20-count package = 15.80 ÷ 20
Using a calculator, we find that the unit price for the 20-count package is 0.79.
Now that we have calculated both unit prices, let's compare them:
- The unit price for the 8-count package is 0.80.
- The unit price for the 20-count package is 0.79.
Comparing these two unit prices, we can see that the unit price for the 20-count package is lower than the unit price for the 8-count package. Therefore, the statement that is true is: "The unit price for the 20-count AA batteries is lower than the unit price for the 8-count AA batteries."
