Business and Economics The candy Shoppe charge $0.08 per copy for quantities up to and including 100 copies. For quantities above 100, the charge is $0.06 per copy. If x represents the number of copies, the price function is p ( x ) = { 0.08 x , for x ≤ 100 , 0.06 x , for x > 100. Find lim x → 100 − p ( x ) , lim x → 100 + p ( x ) , and lim x → 100 p ( x ) .

In the integral dxf1dy (7)², make the change of variables x = ½(r− s), y = ½(r + s), and
evaluate the integral. Hint: Find the limits on r and s by sketching the area of integration in the (x, y) plane along
with the r and s axes, and then show that the same area can be covered by s from 0 to r and r from 0 to 1.
