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

romanna [79]

$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.

ValentinkaMS [17]

The answer is :
$4x - 3 < 32 \\ 4 x < 32 + 3 \\ 4 x < 35 \\ x < \frac{35}{4} \\$
$x < 8.75$
and the only number among the choices that is less than 8.75 is -6
hope it's true
