Answer:
Gavin has 278 more toy blocks than Avery.
Step-by-step explanation:
Gavin has 1,094 toy building blocks. Avery only has 816 toy building blocks.
To know the more number of blocks that Gavin has, we will subtract Avery's count of toys from Gavin's.
We get [tex]1094-816[/tex]
= 278
Hence, Gavin has 278 more toy blocks than Avery.
