The tally table shows the pets that children in a colony would like to keep. Which pet was chosen by exactly 3 more children than the cat?

When you are counting items as you go (e.g. asking 30 classmates their favourite colour), make a tally mark for each answer. To make groups easy to count, the **fifth** mark crosses the previous four: ||||̸. Every group of five jumps out at a glance, and the total is just (groups × 5) + leftovers.
