Part A) About 19/100
Part B) About 4/25
Part C) About 7/20
Part D) About 13/20
Devin borrowed $1,058 at 13 percent for nine months.
We have to calculate the interest paid.
Interest = 
Substituting the values of
Principal = $1058
Rate = 13%
Time = 9 months =
year
Interest = 
Interest = 103.155
= 103.16
So, Devin will pay 103.16 as the interest.
Therefore, Option A is the correct answer.
we can use formula

we can compare
we get
a=x
b=2
now, we can plug that in formula
and we get

now, we can simplify it
