Question

Which is the best buy?
A) A) 5 oz for 42¢
B) B) 24 oz for $1.68
C) C) 18 oz for $1.17
D) D) 26 oz for $2.39

Answer 1

You have to determine how much costs each onze for each option, for example, in option A
\[5oz=42 c\]
you divide by 5
\[1 oz=\frac{ 42 }{ 5 } c=8.4c\]
now, do the same for B, C and D

Answer 2

well, the better "ratio" per pennie will be
5/42 = 0.12
24/168 = 0.143
18/117 = 0.154
26/239 = 0.11

Answer 3

so I'd say you get more "ounces per pennies" on the 18ouncer
