Given:
Debora will sew 3 blankets for each of her nieces.
Let x be the number of nieces and y be the number of blankets.
The number of blankets for x number of nieces =3x.
[tex]y=3x[/tex]Substitute x=n to find the number of blankets for n nieces.
[tex]y=3n[/tex]Hence Debpra will sew 3n blankets for n nieces.
