The unit prices, to three decimal places, are 0.558 and 0.550. ($/oz)
I used a hand calculagtor and rounded off the first one.
To round a number to three decimal places, you need to first identify the fourth decimal place. If the digit in the fourth decimal place is 5 or greater, you round up the third decimal place by adding 1 to it. If the digit in the fourth decimal place is 4 or less, you simply ignore it and leave the third decimal place as it is. Here's an example:
Let's say we have the number 0.55672. To round it to three decimal places:
- The fourth decimal place is 7, which is greater than 5.
- The third decimal place is 6, so we add 1 to it, resulting in 7.
- The rounded number is 0.557.
However, for the purpose of comparing unit prices, rounding to three decimal places is unnecessary. It's advisable to use the exact values to make an accurate comparison.
