Blocks are sold in boxes in bags or as single blocks. Each box has 10 bags in it. Each bag has 10 blocks in it. Tara needs 216 blocks,

So 1 box = 10 bags

1 bag = 10 blocks

so that means that 1 bag is 100 blocks.

So, if 1 bag is 100 blocks and 1 box is 10 bags, tara would need:

2 bags, since 2 bags are 100 blocks, plus

1 box, which is equivalent to 10 blocks, and

6 single blocks.

She will need 3 Boxes with 94 blocks left over
