To find out how much money you will have left after giving S/. 15 of tip to each of your seven nephews, you can multiply the tip amount by the number of nephews and then subtract that total from the total amount of money you have.
Here's a step-by-step calculation:
1. S/. 15 (tip amount per nephew) x 7 (number of nephews) = S/. 105 (total tip amount for all nephews)
2. S/. 101 (total amount of money you have) - S/. 105 (total tip amount) = S/. -4
Therefore, you would be short S/. 4 after giving S/. 15 of tip to each of your seven nephews.
