Supply and the law of supply

AP.MICRO: MKT‑3 (EU), MKT‑3.C (LO), MKT‑3.C.1 (EK), MKT‑3.C.2 (EK)

Problem

Use the figure shown to answer the question.
The figure presents a graph of two supply curves in the first quadrant of the cartesian plane. The horizontal axis is labeled Q and the vertical axis is labeled P. One curve is labeled S 1 and starts at the vertical axis above the origin at coordinates 0 and 10 and moves up and to the right and ends at coordinates 80 and 50. The second curve is labeled S 2 and is directly above and parallel to the first curve and starts at coordinates 0 and 30 and moves up and to the right and ends at coordinates 80 and 70.
Two supply curves
According to each supply curve, what quantities would be produced at dollar sign, 30?
