Answer:

8775

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex].

In this problem, we have that:

[tex]P = 6500, t = 5, I = 0.07[/tex]

So

[tex]E = P*I*t[/tex]

[tex]E = 6500*0.07*5[/tex]

[tex]E = 2275[/tex]

Total

[tex]T = E + P = 6500 + 2275 = 8775[/tex]
