A bakery now makes 150 rolls per batch after increasing its batch size by 25%. How many rolls were in the earlier batch? Enter the number of rolls.

Объяснение

The new batch is 125% of the earlier batch, so 150 / 1.25 = 120. Subtracting 25% of 150 would give 112.50 and would incorrectly use the enlarged batch as the base.
