A material cost is $320 and you receive a 15% discount. What is the discount amount?

Explanation:
A discount means you subtract a portion of the original price, found by multiplying the price by the discount rate. Here, 15% is 0.15, so the discount amount is 320 × 0.15. Break it down: 320 × 0.1 = 32 and 320 × 0.05 = 16, adding up to 48. So you save $48. The new price would be 320 − 48 = 272. Using a fraction, 15% = 3/20, so 320 × 3/20 = (320/20) × 3 = 16 × 3 = 48. This matches the discount amount for 15%. The other options correspond to different percentages, not 15%.
