Annie rounds 280.05 to the nearest hundred = 300
Bobby rounds 280.05 to the nearest ten = 280
Ciro rounds 280.05 to the nearest integer = 280
Denise rounds 280.05 to the nearest tenth = 280.1

the sum of Annie's answer, Bobby's answer, Ciro's answer, and Denise's answer = 300 + 280 + 280  + 280.1 = 1140.1
