Equation:-
---------------
Total cost t =( r-$2)×3
Regular price r = (t+$2)/3
Total cost at last with the $10 per pair:-
–––––––––––––––––––––––––––––
Total cost if one pair is $10
=$10-$2=$8(hiking socks per pair price)
=$8×3=$24(3 pairs of hiking socks price)
Regular price r = (t+$2)/3
Total cost if one pair is $10
=$10-$2=$8(hiking socks per pair price)
=$8×3=$24(3 pairs of hiking socks price)
