(Linear Functions) The average price for a new refrigerator over the past 50 years can be approximated by a linear function. The average prices at two different points in time are shown below. e Years since 1970: 12 Price of a new refrigerator: $624 e Years since 1970: 36 Price of a new refrigerator: $1104 If the average price for a new refrigerator is a linear function based upon the years since 1970, determine the slope (with correct units) and give a practical interpretation. (If necessary, round any decimal values to 2 decimal places.) (A) Slope: 0,05 301aTS year Interpretation: The average price of a new refrigerator has increased by $0.05 each year since 1970. (B) Slope: 0.05 2> dollar Interpretation: The average price of a new refrigerator has increased by $0.05 each year since 1970. dollars (C) Slope: 20 year Interpretation: In 1970 the average price of a new refrigerator was $20. dol]ars (D) Slope: 20 year Interpretation: The average price of a new refrigerator has increased by $20 each year since 1970. E) Slope: 202 (5 Slope: 20'3 ar Interpretation: The average price of a new refrigerator has increased by $20 each year since 1970
