After evaluating the final answer is 4.

Step-by-step explanation:

Given,

j = 25

k = 5

We need to evaluate the given expression.

Solution,

Firstly we will substitute the given values;

Now we will apply 'PEDMAS' rule.

The first operation that performed will be division, and we get;

Now the second operation is multiplication, and we get;

Now we subtract using subtraction property and get;

Hence after evaluating the final answer is 4.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
