Final answer:
Annalise earned a total of $55.32 by adding $36.82 and $18.50. The additive inverse of her earnings is -$55.32. If she spends this amount exactly, she will end the week with zero dollars.
Step-by-step explanation:
The question asks us to find the total amount Annalise earned by adding $36.82 and $18.50, the additive inverse of the total, and describe a situation where Annalise could end the week with zero dollars.
To find the total amount Annalise earned, we perform the following calculation:
- Add $36.82 and $18.50 together.
- The sum is $36.82 + $18.50 = $55.32.
The additive inverse of $55.32 is simply the negative of this value, which is -$55.32. The additive inverse, when added to the original amount, will result in zero.
An example situation would be: Annalise has $55.32 at the start of the week. If she were to spend $55.32 on school supplies, her balance would be $55.32 + (-$55.32) = $0, meaning she will end the week with zero dollars.
