The grocery store has a sale on canned tomatoes: 4 cans for $5.00. Find the unit rate (cost per can).

For every can, it would be $1.25.  1 can= $1.25

Step-by-step explanation:

For every 4 cans, it is $5, 4:5

if you divide both sides by 4. it would 1:1.25

So, for every can, it would be $1.25

Number of sections in mosaic=100 section

Number of tiles required in each section=31.5 tiles

Total number of tiles required in mosaic

                      =31.5 × 100

                      =3150 tiles

5=Tenth place

1=Unit Place

3=Tens Place

As 31.5 has to be multiplied by 100, there is single digit after decimal, so 0, will be placed at right end of number to get correct number of tiles.
