Develop an expression that summarizes delivery charges. (Enter your answers as dollar amounts to 2 decimal places (x1-weight x2-distance). Omit the "$" sign in your response.) b. Determine the delivery charge for transporting a 45-pound parcel 25 miles. (Do not round your intermediate calculation. Round your answer to 2 decimal places. Omit the "$" sign in your response.)

Explanation / Answer

(a) Expression that summarizes delivery charges: Let the weight be X1 pound Let the distance be X2 miles The cost per pound = 30% of X1 or $0.30 X1 per parcel The cost per mile = 25% of X2 or $0.25 X2 per parcel Handling cost = $35 per parcel Delivery chages represents by Y Y = $ 0.30   X1 + $ 0.25 X2 + $ 35 (b) Computation of delivery charge for transportation of 45 pound parcel and 25 miles: X1 = 45 pound X2 = 25 miles Putting the value of X1 and X2 in above expression we get delivery charges: Y = $ 0.30   X1 + $ 0.25   X2 + $ 35 Y = ($ 0.30*45) + ($0.25*25) + $ 35 Y = $ 13.50 + $ 6.25 + $ 35 Y = $ 54.75
