As a self-employed seamstress, you know that it takes 7 yards of material to make 3 jackets. you bought 15 yards of material to make 7 jackets. did you buy enough material? if not, how much were you over or under?

you bought a little bit less than you needed

Step-by-step explanation:

so if it takes 7 yards to make three jackets and you have 15 yards this is what you have to do:

7 yards=3 jackets

7+7=14 so with 14 yards you can make 6 jackets

but you bought fifteen and 7 divided 3 equals 2.3 ( or what it takes to make one jacket)

so if you wanted to have exactly enough material to make 7 jackets you need  16.3 yards

No, you need 1 1/3 more yards.
