Did you know that the number of possible ways the four girls can dress up, knowing that each girl can only use the same swimsuit once, can be calculated using a concept called permutations? The formula for calculating permutations is n! / (n-r)!, where n is the total number of items or options, and r is the number of items or options being chosen at a time. In this case, since each girl can only wear one swimsuit, n would be 4 (number of girls) and r would also be 4 (since they are choosing all of the swimsuits). Plugging these values into the formula, we get 4! / (4-4)! which simplifies to 4! / 0!, and since 0! is equal to 1, the answer is 4! or 4 factorial, which equals 4 x 3 x 2 x 1 = 24. So, there are 24 possible ways the girls can dress up by borrowing and using the swimsuits.
