Denise should pay 1200 dollars for the 1st jacket and (1-0.35)*1200 = 0.65*1200 = 780 dollars for the 2nd jacket, according to the problem. (We do not consider tax). In all, she must pay 1200 + 0.65*1200 = (1 + 0.65)*1200 = 1.65*1200 = 1980 dollars. If she pays $2000 to a cashier, she will get change back of $2000 - $1980 = $20. ANSWER
