Question

each can of paint will cover 450 tiles. Augustin is painting 300 tiles in his bathroom, 675 in his kitchen, and 100 in his hallway. How many cans of paint does he need to buy?

Answer 1

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

Answer 2

He will need to buy 3 cans.

Explanation:

First we need to know how many tiles he will paint.

The total amount of tiles he will paint is 300 + 675 + 100 = 1075 tiles.

We know that a can of paint will cover 450 tiles, therefore, we need to divide the total amount of tiles between the number of tiles covered by can:

1075/450 = 2.38.

He will need 2.38 cans of paint. But he cannot buy this number of cans, therefore he will have to buy 3 cans and will have some paint left.
