Which would be the best buy?

Question

Find the best buy on pasta sauce (1 qt is 32 oz).
A)1 qt for $1.29
B)45 oz for $1.59
C)48 oz for $1.79
D)1 qt 16 oz for $1.99

Answer 1

A) 32 oz - $1.29
B) 45 oz - $1.59
C) 48 oz - $1.79
D) 48 oz for $1.99
First, eliminate answer D.

if you look carefully, between A and B, 13 oz is worth $1.59-$1.29 = $0.30
and for B and C, 3 oz is worth $1.79-#1.59 = $0.20

Thus, we eliminate answer C.

so you need only to calculate
A) $1.29 / 32 =0.0403...
B)$1.59 / 45 =0.0353...

Thus, B is the answer.

Answer 2

Convert all the qt. to oz., then divide the price by the oz. Assuming the quality is the same, the best buy is the lowest price per oz.

Jeez I'm starved, think I will make some pasta with B.

Answer 3

First find the unit price. Rate per Oz.

(A) $ 1.29 / 32 = $ 0.040313

(B) $ 1.59 /45 = $ 0.035333

(C) $ 1.79 / 48 = $ 0.037292

(D) $ 1.99 / (32+16) = $ 0.041458.

The best to buy is (B), provided if the quality is good.

Answer 4

1.29/32
1.59/45
1.79/48
1.99/48

the best deal is C
