A local sports store is selling its hiking socks for $2 off the regular price of a pair of socks. You buy 3 pairs of hiking socks. Write an equation that gives the total cost t as a function of the regular cost r of a pair of socks. Then find the total cost if the socks regularly cost $10 per pair.
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)
