Answer 1

9514 1404 393

Answer:

$16.345 / kg

Explanation:

You know there are 1000 grams in 1 kilogram. (The prefix kilo- means 1000.) So 550 grams is 550/1000 kg = 0.55 kg.

The price per kilogram is found by dividing the price by the corresponding number of kilograms:

unit price = $8.99 / (0.55 kg) = $16.3454545... (2-digit repeat) / kg

Rounded to 3 decimal digits, the unit rate is ...

unit rate = $16.345 / kg
