Answer:
<h3>Children's books</h3>
- Number = c
- Cost of each = $5
- Total of children's books = 5c
<h3>Adult books</h3>
- Number = a
- Cost of each = $9
- Total of children's books = 9a
<h3>The equations reflecting the totals are</h3>
- Books ⇒ c + a = 500
- Total cost ⇒ 5c + 9a = 3940
2 by 7 + – is equals to 1 so we can say that x.
x=1-2/7
x=7/7-2/7
x=5/7

You will need to make an equation for this. First, you know that he always pays $5 monthly, keep this in mind. Then it is given that his bill last month was 13.46 and that we need to know the minutes spent. for every minute, 9 cents or $0.09 is charged. In order to find out the time he spent, write the equation as such:
$5+$0.09(minutes)=$13.46 and solve from there
