Final answer:
The overall change in Joaquin's bank account for January and February can be found by summing the decrease from January (if any) and the addition in February. We assume a decrease of $85.71 in January and an addition of $65.71 in February results in an overall change of -$20.00, which does not match any of the provided options.
Step-by-step explanation:
To find the overall change in Joaquin's bank account for January and February combined, we need to consider both the decrease and the increase in his account balance for the respective months. If the question implies that there was a decrease in January (which is not provided in the question, but generally, a negative sign would indicate a decrease), and then Joaquin added money in February, we would subtract the decrease from the increase to find the overall change.
Lets assume there was a loss or deduction in January (the value of that loss or deduction is not provided in the data). Following that assumption, when he adds $65.71 to his account in February, we would calculate the overall change by adding this amount to the January decrease. If the January decrease was indeed $85.71 (a negative value) then:
- January change: -$85.71 (negative indicating loss)
- February change: +$65.71 (positive indicating gain)
Overall change = February change (+$65.71) plus January change (-$85.71)
Overall change = -$85.71 + $65.71 = -$20.00
