Answer:
38.5 yards used
Explanation:
Yes he has enough fabric
to get the answer you must take the total number of dresses (8) and multiply it by 3 1/2 (3.5) because thats how much it takes to create one dress.
3.5 x 8 = 28
Now take the number of scarfs (14) and multiply it by 3/4 (0.75) because thats now much it takes to create a single scarf
0.75 x 14 = 10.5
now you add both of the answers
10.5 + 28 = 38.5
since 38.5 < 40 it means that he has enough fabric to create all the costumes for the musical
