Answer 1

Answer:

Part a) Cereal A $0.59\frac{\ }{oz}$

Part b) Cereal B $0.27\frac{\ }{oz}$

The best buy is Cereal B

Step-by-step explanation:

we know that

To find the unit price divide the price by the quantity

Let

x------> the price

y------> the quantity

U------> the unit price

so

$U=\frac{x}{y}$

Part a) we have

Cereal A

$x=\ 5.90$

$y=10\ oz$

substitutes

$Ua=\frac{5.90}{10}=0.59\frac{\ }{oz}$

Part b) we have

Cereal B

$x=\ 6.48$

$y=24\ oz$

substitutes

$Ub=\frac{6.48}{24}=0.27\frac{\ }{oz}$

Compare the unit prices

$Ub$

therefore

The best buy is Cereal B

Answer 2

10z box = $5.90
1 oz = $5.90 ÷ 10 = $0.59

24 oz box = $6.48
1 oz = $6.48 ÷ 24 = $0.27

24 oz box is cheaper, it is a better buy
