First, we multiply the ones:

Next, we multiply the tens:

Therefore, $187 \times 42 = 7 , 854.$

We already have the ones and tens multiplied:

So, we add the two final rows:

So, $2,493 \times 36 = 89 , 748.$

Therefore, the factory produces a total of $89,748$ cookies each day.

To calculate the total amount of dollars in admittance fees the museum made, we need to multiply $23,772$ by $43.$

So, $23,772 \times 43 = 1 , 022 , 196.$

Therefore, the museum made $\$1,022,196$ in admittance fees in January.
