Answer:
$6.09875 or $6.10
Explanation:
We need to take 7/8 of the price ($6.97)
7/8 is .875
Then multiply .875 by $6.97 to get $6.09875, which we can round to $6.10
(If they were buying a full yard, we could test this way by doing 8/8, which is 1, and multiplying it by the price, which would give us the same thing).
Hope this helps
