Answer:
690.1
Step-by-step explanation:
13.4 x 10.3 x 5
Given points,
(x1,y1)=(2,9)
(x2,y2)=(10,6)
now the distance between two points is,

$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.
