pls explain

4 dollars per pair of socks.

Step-by-step explanation:

You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.

Another way to solve this is by forming a linear equation.

y = 4x

Any number plugged into x to represent pairs of socks will give the cost, y.

For example: y = 4(7), which simplifies to y = 28.

This means that for every one pair of socks, it costs four dollars.

yes and $4

Step-by-step explanation:

7*4=28

11*4=44

13*4=52

15*4=60
