A proportional relationship between the number of pairs of socks that Shelley buys, x, and the total cost (in dollars), y, can be written as:
y = kx
where k is the constant of proportionality. This means that for every increase in the number of pairs of socks, the total cost will also increase proportionally.
For example, if Shelley buys 3 pairs of socks and the constant of proportionality is 2, the total cost would be:
y = 2 * 3
y = 6 dollars
If she buys 5 pairs of socks, the total cost would be:
y = 2 * 5
y = 10 dollars
In this scenario, the constant of proportionality remains the same, indicating that the cost per pair of socks is consistent regardless of the quantity purchased.
Shelley loves to wear socks with crazy patterns. She finds a great deal for these kinds of socks at her favorite store, Rock Those Socks.
There is a proportional relationship between the number of pairs of socks that Shelley buys, x, and the total cost (in dollars), y.
