Question

Cameron wanted to buy some pens.They had 18 pens for $ 6.84 for 30 pens for $8.40 which is a better deal?

Answer 1

I would say 18 pens for $6.84 is a better deal because its cheaper.

Answer 2

$6.84 divided by 18= .38 which means 38 cents per pen

$8.40 divided by 30= .28 which means 28 cents per pen

so $8.40 for 30 pens is a better deal than 18 pens for $6.84 by ten cents.
