Option 1: 32.9 dekadollars and 329 decidollars
Option 2: 0.329 dekadollars and 3.29 decidollars
Option 3: 329 dekadollars and 3.29 decidollars
Option 4: 3.29 dekadollars and 32.9 decidollars

Answer 1

To express the price of a jar of peanut butter in dekadollars and decidollars, divide $3.29 by 10 to get 0.329 dekadollars. Decide dollars remain the same as the dollar amount.

Step-by-step explanation:

To express the price of a jar of peanut butter in dekadollars and decidollars, we need to convert the dollar amount to the desired units. A dekadollar is equivalent to 10 dollars, whereas a decidollar is equivalent to 100 dollars.

To convert the price to dekadollars, we divide $3.29 by 10, which gives us 0.329 dekadollars. To convert the price to decidollars, we don't need to make any changes since a dollar is already equivalent to a decidollar.

Therefore, the correct option is Option 2: 0.329 dekadollars and 3.29 decidollars.
