A T-shirt costs 4 times as much as a pair of socks. a T-shirt costs $16.
alukav5142 [94]
Answer:
D. 4s = 16

Explanation:
We are given that a T-shirt is 4 times the price of the sock.
This means that if we multiply the price of sock by 4, we will get the price of the T-shirt.
In equation form:
price of T-shirt = 4*price of sock

We are given that:
cost of the pair of socks is "s".
cost of T-shirt = 16

Substitute in the above equation, we get:
16 = 4s

Hope this helps :)
