Answer 1

Answer:

b) 5×12+3×2

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)
