Answer:

  • For 15 pens, the cost is $7.2

Explanation:

We know that:

  • 8 pens = $3.84

Work:

  • 8 pens = $3.84

Divide the RHS:

  • => 1 pen = 3.84/8
  • => 1 pen = 0.48

Multiply the RHS:

  • => 15 pens = 0.48 x 1
  • => 15 pens = $7.2

Hence, for 15 pens, the cost is $7.2

Hoped this helped.

The cost of 15 pens is $7.20.


3.48 divided by 8 is 0.48. Multiply that by 15 and you get 7.2 or $7.20
