A store sells packs of pencils that each contain a different number of pencils. The different packs are listed:
$1.80 for 6 pencils
$2.00 for 10 pencils
$4.80 for 12 pencils
$4.50 for 15 pencils
Which pack of pencils has the lowest price per pencil?
To find the price per pencil for each pack, divide the price by the number of pencils:
$1.80 for 6 pencils: $1.80 / 6 = $0.30 per pencil
$2.00 for 10 pencils: $2.00 / 10 = $0.20 per pencil
$4.80 for 12 pencils: $4.80 / 12 = $0.40 per pencil
$4.50 for 15 pencils: $4.50 / 15 = $0.30 per pencil
Therefore, the pack of pencils with the lowest price per pencil is $2.00 for 10 pencils, which is $0.20 per pencil.
