Question

Jennifer had $24 to spend on five pens. After buying them she had $14. How much did each pen cost?

Answer 1

$24-$14= What Jennifer spent=$10
She spent $10 on five pens which means one pen costs $10÷5=$2
One pen is equivalent to $2 Each.

Answer 2

Jennifer used $24-14=10 dollars in total.
The $10 was spend on five pens, each pen costing say, x, dollars.
The equation would be 10 = 5x
x = 10÷5= $2

So each pen costs $2 :)
