Mrs. Lewis bought 100 yards of ribbon. She used some of the ribbon to decorate dresses .Now she has 67 yards of ribbon remaining. How many yards of ribbon did Mrs. Lewis use to decorate the dresses?

33 yards

Step-by-step explanation:

To find the number of ribbons that she used to decorate the dresses can be gotten by subtracting the amount of ribbon left from the total amount of ribbon she had.

She bought 100 yards. She has 67 yards left.

Therefore, the amount of ribbon she used for the dresses is:

100 - 67 = 33 yards

i think that you should ask google for the answer to that problem because if we don't know it google does
