Socks cost $2 per pair. The cost of n pairs is $2n. John says that the cost of 6 pairs is $26 and the cost of 7 pairs is $27. Is this correct? What did John do wrong?
John just added the number 6 and 7 after the 2 and he thought that if 2 times n is 2n then he thought he thought that, 2 multiply by 6 would be 26 and 2 times 7 is 27 by the example of 2n. Sorry if I confused you
