Answer:
Assuming that he only wears the shoes as matched pairs, and only wears one pair of pants and one T-shirt at a time… he has 16 combinations.
Let's say he has a brown pair of shoes, and a white pair.. and let's label his shirts “A",”B",”C", and “D".. and his pants “1” and “2”.
His combinations are:
A1brown. B1brown. C1brown. D1brown
A2brown B2brown C2brown D2brown
A1white B1white C1white D1white
A2white B2white C2white D2white
That's 16 combinations.. its 4(shirts) x 2(pants) x 2(shoes).
If he can mix his shoes, then the answer is 32, because he doubles his shoe combinations. Instead of just brown/brown and white/white, his possibilities are now brown/brown, brown(left)/white(right), white(left)/brown(right) and white/white.

Step-by-step explanation:
Here the number of T-shirt is 5.
The price of each T-shirt is$12.
Therefore the total price of the T-shirt is 5×12.
Number of socks is 3 pairs.
Price of each pair of sock is$2.
Therefore total price of socks=3×2.
Thus total dollars spent in buying T-shirt and socks is (5×12+3×2)
