Computer desks can be purchased for $10.90 a dozen or in case of 60 $80 a case. Use unit prices to tell which prices is the best deal.

The correct answer is:

The better deal is $10.90 for a dozen.

Explanation:

A unit rate is a rate with a denominator of 1. This means we want to know the price of one individual desk for each bulk package.

$10.90 for a dozen desks:

Divide 10.90 by 12:

10.90/12 = 0.9083 ≈ $0.91 per desk.

$80 for 60 desks:

Divide 80 by 60:

80/60 = $1.33 per desk.

The lowest cost per desk is in the $10.90 for a dozen deal.
