Question

Which is least expensive per oz rounded to the nearest cent: 20 oz for $1.79 or 2 lb 2 oz for $2.59?

A.) 20 oz
B.) 2 lb 2 oz
C.) Neither

Answer 1

B.) 2 lb 2 oz

Explanation:

$1.79 for 20 ounces gives us

1.79/20 = $0.0895 ≈ $0.09 per ounce.

1 lb = 16 oz.; this means that 2 lb = 2(16) = 32 oz.

$2.59 for 2 lb 2 oz then gives us

2.59/34 = $0.07617647059 ≈ $0.08 per ounce.

The second choice is cheaper by 1 cent.

Answer 2

20 / 1.79 = 11.17
11.17 = 11.2

2 lb 2 oz / 2.59 = 0.82
0.82 = 0.8

So the answer is B) 2 lb 2 oz.

Hope this Helps!
