Answer:

614.25

Step-by-step explanation:

The amount of interest is computed using ...

... I = Prt . . . . . where P is the principal amount, r is the annual interest rate, and t is the number of years.

Here, the interest is ...

... I = 520×0.075×(2 5/12) = 39×29/12 = 94.25

The total amount due, interest plus principal, is ...

... 94.25 + 520 = 614.25

The formula to find the total amount is


A=p (1+rt)

A total amount. ?


The interest should be bear on the borrowed amount which is 70% of total cost 364 (520×0.7)

P amount borrowed 364


R interest rate 0.075


T time 2+(5÷12)=2.42 years


A=364×(1+0.075×2.42)

A=430.066....answer


Hope it helps!
