8. Write an equation in standard form for the given circle. (1 point)
(x-3)^2+(y+2)^2=9
(x+3)^2+(y-2)^2=9
(x-3)^2+(y-2)^2=9
(x+3)^2+(y+2)^2=9

Let s and l represent the numbers of small and large ICs sold that day. The problem statement gives rise to two equations.
.. s + l = 2200
.. 1.50s +4.00l = 5050

Solving these by your favorite method gives
.. s = 1500
.. l = 700

1500 small ICs and 700 large ICs were sold.
