The Sangguniang Kabataan of Barangay STAR plans to sponsor portable disinfecting kits for 125 frontliners living in their area. Each set of kit is worth ₱150.00. If they are to buy from a factory that sells that particular kit, they will be given a 30% discount. If they will buy from the store, they will be given a 25% off the price for each set. Where will they have a cheaper purchase and by how much? Explain.

What can you say about the relationship of the percentage of discount and the trade discount being deducted from the list price?
