You have to add all of the tiles that he needs painting. 675+300+100=1075. Then to figure out how many paint cans you need, divide 1075 by 450. It equals 2.388... so, you need to round up or else you will be missing some tiles. The final answer is 3 paint cans. Hope this helps
He will need to buy 3 cans. ;
Augustin needs to buy a total of 3 cans of paint to cover 1,075 tiles. Each can covers 450 tiles, resulting in 2.39 cans required. He rounds this up to 3 cans since he cannot purchase a fraction of a can.
