Foundation November 2023 Paper 1 Q8

8 Shamira uses a tally chart to record the vehicles passing her school.

Here is her chart with the tallies.

Each 5-bar gate \(\big(\cancel{||||}\big)\) represents 5 vehicles.

(a) Shamira says,

“The number of cars is more than the total of the other vehicles
because cars have four 5-bar gates and the others only have three 5-bar gates.”

Is she correct?
