Jenny is comparing the cost of two packages for socks 1 packages has eight pairs of socks for $12 another packages has three pairs of socks for $6 are the rates equivalent

Think about it like this. The rate is how much bang you're getting for your buck. In other words, how many pairs of socks are you getting for a given amount of money. 

Lets say I'm spending 12 dollars.

The first plan gives me 8 pairs. It's charging me 12/8 = 1.5 dollars for each pair of socks.

The second plan gives me 6 pairs. (3 pairs for 6 dollars, so if you double it then you get 6 pairs for 12 dollars). It's charging me 12/6 = 2 dollars for each pair of socks.

Since 2 > 1.5, I can say Plan 2 has a higher rate than Plan 1.
