Answer:
3/4 of a foot will cost $2.25.
Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars
[tex]x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25[/tex]
So
3/4 of a foot will cost $2.25.
