Question

Mr. Lemos is shopping for a particular brand of protein bar. Three different stores sell this particular brand of bar. Mr. Lemos considers the advertised price at each store. Store A: 10 bars for $3 Store B: 4 bars per dollar Store C: $0.20 per bar Which store offers the best deal? Explain the reasoning that supports your answer.

Answer 1

For store A, 10 bars for $3,

Therefore, the cost of one bar is,

$\frac{3}{10}=0.3$

For store B, 4 bars per dollar.

Therefore, the cost of one bar is,

$\frac{1}{4}=\text{0}.25$

For store C, it is $0.20 for one bar.

From the rates, we can see that the best deal is for store C.
