b/c if lets say it was $2 before the price was doubled after it waas doubled it would be $4 if it had been risen by 50% it would have been $3 but if it waas risen by 100% it would be $4
Divide 4.10 by 7 to get about 0.59 (round up because you can't get part of a penny) and that gives you 1/8 of a yard's price. Then multiply that by 8 to get a full yard for $4.72.
