Answer:

1 1/4 yards

$20

Step-by-step explanation:

The amount of fabric more that she needs can be determined by subtracting the sum of the yards needed for the shawl and the dress from the fabric she has

sum of the yards needed for the shawl and the dress =

$2\frac{1}{2} + 1\frac{3}{4}$

$3\frac{2 + 3}{4}$ = $3\frac{5}{4}$ = $4\frac{1}{4}$

Yards needed

$4\frac{1}{4} - 3$ = $1\frac{1}{4}$

cost of dance outfit = $16 x $1\frac{1}{4}$

$\frac{5}{4}$ × $16 = $20
