Question

which expression represents the cost per socks.

17.10d=5

5x17.10=d

5 divided by d=17.10

17.10=5d

 

Answer 1

5*D = 17.20

 

or 17.20 = 5D       (you need to decide whether its 17.20 or 17.10 for the 5 pairs, the question stated 17.20, so that is

 

what I used. Therefore none of your answers is correct.

 

The correct answer therefore is 17.20 = 5D
