She pays in total $1350 after the 12 months
Step-by-step explanation:
The given is:
1. Daniela borrowed some money from her parents she agreed to pay
$30 at the end of the first month
2. She agreed to pay $15 more each additional month for months
We need to find how much money she pays in total after the 12 months
The formula of the sum of n terms of an arithmetic series is
, where a is the 1st term, d is the
common difference between each two consecutive terms, and n the
position of the term
∵ She will pay $30 at the end of the first month
∴ a = 30
∵ She will pay $15 more each month
∴ d = 15
∵ She will do that for 12 months
∴ n = 12
Substitute these values in the formula of the sum above
∴
∴
∴
∴
∴
She pays in total $1350 after the 12 months
