Question

Target is selling 3 batteries for 4.80 and Walmart is selling 12 batteries for _______. Which one is the better buy?

1) 1.20
2) 2.40
3) 3.60
4) 4.80

Answer 1

The cost per battery at Target is $1.60. Walmart has four price options. Option 1 at Walmart is the best deal at $0.10 per battery, making it cheaper compared to Target.

Step-by-step explanation:

To determine which store is offering a better deal for the batteries, we need to calculate the cost per battery for both Target and Walmart and then compare the results.

At Target, 3 batteries are sold for $4.80. So the cost per battery at Target is $4.80 ÷ 3 = $1.60 per battery.

Now, let's check the options provided for Walmart's price for 12 batteries and find the cost per battery:

1. $1.20 ÷ 12 batteries = $0.10 per battery
   
2. $2.40 ÷ 12 batteries = $0.20 per battery
   
3. $3.60 ÷ 12 batteries = $0.30 per battery
   
4. $4.80 ÷ 12 batteries = $0.40 per battery
   

Comparing the cost per battery at Target to the options for Walmart, the best option would be the one that gives us the lowest cost per battery. Option 1 at Walmart is the best deal, providing batteries at $0.10 each compared to Target's $1.60 each.
