Question

Mandy finds she can get a discount on corn cobs if she buys in bulk. She can get 100 kilograms of corn cobs for $160 from Matt, on condition that she buys at least 100 kilograms. From another supplier, Robert, she can buy small quantities of corn cobs (100 or less) for $1 per cob or larger quantities (more than 100) for $0.60 per cob. Mandy charges all of her customers by weight, so she gets $5 per kilogram of corn cobs or $1.25 for an individual corn cob. If Mandy is going to sell over 100 kilograms of corn cobs today, what is the best profit per corn cob she can make?
A: $0.65 B: $0.85 C: $0.80 D: $0.60 E: None of these.

Answer 1

Answer:

he gets $ 1. 60 .kg

Step-by-step explanation:

From Matt, he gets corn cobs at $1.60 a kg ($160/100). She sells at $5/kg or $1.25/pc. Assuming she did not add up even a little on the per piece selling price, her selling price tells us there are 4 pcs of corn cobs in a kg ($5/1.25 =4). So, for $1.60/kg, his buying price is equivalent to $0.40/pc ($1.60/4)

She can make the best profit if she buys in kg (over 100kg) and sells it in pieces (retail).

Best Profit = selling price per pc - buying price per piece

Best profit = $1.25 - $0.40 = $0.85

From Robert, she gets at $0.60 if the quantity is over 100kg and sells at $1.25.

Best profit = $1.25 - $0.60 = $0.65

Therefore, the answer is $0.85.
