Karly is making a new dance outfit. She needs 2 ½ yards of fabric for the shawl. She needs 1 ¾ yards of fabric for the dress. If she has 3 yards of fabric, how much more does she need. If each yard of fabric costs $7.98, how much money does Karly need?
fabric required: 2 1/2 + 1 3/4 = 3 + 1/2 + 3/4 = 4 1/4 yards
fabric in possession: 3 yards
============================
need to purchase 4 1/4 - 3 = 1 1/4 yards
total cost = (1 1/4) * ($7.98) = $9.98 (to the nearest cent)
