Answer:
Most expensive thing she can afford after 7 years is of worth 2560$
Explanation:
We need to calculate the interest on $2000 at 4% interest per year after 7 year(s).
The formula we'll use for this is the simple interest formula, I = P*r*t, I is the interest after t years, r is interest rate and P is the invest amount.
P = 2000$, r = 4/100 = 0.04, t = 7 years
So , I = 2000* 0.04 * 7 = 560$
Total amount she can retrieve from bank = P+I = 2000 + 560 = 2560$
Most expensive thing she can afford after 7 years is of worth 2560$
