The art club is selling their handmade jewelry to raise money for new paints and brushes. Earrings were sold for $6 a pair and necklaces were sold for $12.50 each. They sold a total of 30 items and made $264.50.

Which system of equations best represents the situation above?

Note: In all of the choices below, e represents money earned, p represents price, and n represents number of items sold.

a

Earrings: e=6 (30-n)

Necklaces: 264.50-e=12.50*n

b

Earrings: e=12.50 (30-n)

Necklaces: 264.50-e=6*n

c

Earrings: e=6 (n-30)

Necklaces: e-264.50=12.50*n

d

Earrings: e=30-n

Necklaces: 264.50-e=n
