Ответ:
Here, we need to find the cost of each pen, including tax. Since, information about tax was not given, so we will not consider this.
Total money Amy had = $ 26.
She is left with $ 14.30. The money she spent will be -
Total money - Money left = Money spent
$ 26 - $ 14.30 = $ 11.70
Total money she spent on 10 pens = $ 11.70
So, money spent on = $ 11.70 ÷ 10 = $ 1.17
So, the cost of each pen will be = $ 1.17
