Question

Which is the better deal? Pepsi 12 oz for $0.99 • 32 oz. for $1.99 • 64 oz for $2.99 • 128 oz for $4.99 O 12 oz for $0.99 64 02. for $2.99 32 oz $ 1.99 128 oz for $4.99

Answer 1

To know which one is a better deal, we have to find the maximum rate of volume to dollar.

We have to calculate it for each one as:

`U_1=\frac{12\text{ oz}}{0.99\$}\approx12.12\text{ oz/\$}`
`U_2=\frac{32\text{ oz}}{1.99\$}\approx16.08\text{ oz/\$}`
`U_3=\frac{128\text{ oz}}{4.99\$}\approx25.65\text{ oz/\$}`
`U_4=\frac{64\text{ oz}}{2.99\$}\approx21.40\text{ oz/\$}`

The option that gives us more volume per dollar is the option of 128 oz for $4.99.

Answer: 128 oz.
