How long will it take for a class to get clean! S,L,J

The Question: Let’s imagine that we tested the air in your classroom and found 7 different kinds of mould. Eek! The cleaner says that it takes 5 days for each mould to be eradicated (removed). If the school had to remove each mould one at a time, how long would it take to remove all the mould from the classroom?

Simple way 7x5=35 👍

Or the long way:🕵

There's a class that has 7 air moulds and it takes 5 days to get 1 air mould out.
