Answer:
1) +80
2) -1520
Step-by-step explanation:

1) We are told that Reuben received 80 dollars. Thus, it means he received an increase in the amount of money he already had. Thus, the signed number will be +80.

Thus, the signed number will be negative since there is a decrease in number of cars.
Thus, signed number = -1520
