Kudos for a correct solution.Hi

If a hotel orders twice as many papers on Sunday as it does the rest of the days

of the week

I thought it as number of papers on sunday=x --> number of papers on other days =2x

But it is other way round

I often get this kind of equations wrong.

can anyone please explain ...how to remember , any tip?

Thanks
