The first one because if you add all the positives you get 4 and then if you add all the negatives you get 7 so then you do 4+(-7)= -3
350 dollars for the kayak + 1.50 for the fee + the 10.23 interest for the three months = 361.73
All you have to do is multiply: -3.25•-1.56=5.07. A negative times a negative is a positive :)
