Question

You need to buy laundry detergent and your favorite brand comes in three different sizes. Size 1 costs $7 and is enough for 28 loads, size 2 costs $14.72 and is enough for 64 loads, and size 3 costs $24 and is enough for 100 loads.
Which size is the best deal?

A. They are all the same
B. Size 1
C. Size 2
D.

Answer 1

\[\frac{ 7 }{ 28 } = $0.25\]
\[Size~ 1: 0.25 \times 28 = $7 (No ~ savings)\]
\[Size ~ 2: $0.25 \times 64 = $16 (Savings: $1.28)\]
\[Size~ 3: $0.25 \times 100 = $25 (Savings: $1)\]
