The smallest total was 308 cans. 3.The range of the total can was 421. 4. The total number of cans collected from all classes was 2,130

Answer 1

????? wotz the quesshun ?????????

me thank yu tri tu sae...yu hav 5 numbers, sum=2,130, small=308, raenj=421

& 2 numbers =300+, 2=400+, & 1=500+

then, big=small+raenj=308+421=729...this impli the 500+number=729

3 av numbers...sum=2130-729=1401=(300+x)+(400+y)+(400+z)=1100+x+y+z

or x+y+z=1401-1100=301

Kontradikt...3 numbers add up tu 301 meen at leest 1 gotta add 100+

300+100+=400+

that brake the rules
