~Denki Kaminari here~
so what we're going to do is, find the cost of wrapping paper per foot,
6.03 divided by 9 = 0.67
now we're going to convert the 9ft into yards,
1 yard= 3ft so, there are 3 yards.
now that we know that there are 3 ft in one yard, we are going to multiply 0.67 by 3
0.67x3= 2.01
so, we got $2.01 per yard
hope this helps :D
