Please answer this question step by step with formula. Sam Store orders 200 pens that list for $0.5 each, 150 pads that list for $0.7 each, and 100

pencils that list for $0.2 each. The single trade discount rate for the order is 15%. Find the net

price of the order and the amount of discount.​

Net price = $191.25

Discount Price = $33.75

Step-by-step explanation:

Cost of one pen = $0.50

Cost of 200 pen = 200 × 0.50 = $100

Cost of one pad =$0.70

Cost of 150 pads = 150 × 0.70 = $105

Cost of one pencil = $0.20

Cost of 100 pencils = $20

Total cost of the order = 100 + 105 + 20 = $225

Discount % = 15% of 225

Discount price = ( 15% × 225) = $33.75

Total amount after discount = 225 - 33.75 = $191.25
