Question

Jed goes to the deli to purchase turkey that costs $6.71 per pound. State regulations indicate that the scale used in the deli must be accurate to within 1 20 pound. According to the scale, Jed's purchase weighs one-fourth pound and costs $1.68. How much might he have been undercharged or overcharged due to a scale error

Answer 1

Answer:

$0.333

Explanation:

Given :

Price per pound = $6.71

Accuracy should be within 1/20 pound

Weight of Purchase = 1/4 pound

Cost of purchase = $1.68

Since accuracy is within 1/20 pound ;

The weight of purchase will be within :

(1/4 - 1/20 ; 1/4 + 1/20)

(0.2 ; 0.3)

The weight of purchase would be within (0.2 ; 0.3) including factoring in the accuracy level.

Price per pound = $6.71

If weight is 0.2 pounds ; ($6.71 * 0.2) = 1.342

If weight is 0.3 pounds ; ($6.71 * 0.3) = 2.013

Difference :

$(2.013 - 1.68) = $0.333

Owing to scale error, Jed might have been under charged or overcharged an amount of $0.333
