Answer:
42 yards
Step-by-step explanation:
Given that Jennie could mkae 7 quilts out of 21 yards of material:
We could establish a proportion to find the value of x yards of material required to make 14 quilts:
21 yards/7 quilts = x yards / 14 quilts
[tex]\frac{21}{7} = \frac{x}{14}[/tex] ⇒ Perform cross-multiplication:
7x = 21 × 14
7x = 294
Divide both sides by 7 to solve for x:
[tex]\frac{7x}{7} = \frac{294}{7}[/tex]
x = 42 yards
Therefore, Jennie needs 42 yards of material in order to make 14 quilts.
