Answer:
£2947
Explanation:
the formula for simple interest is interest = prt.
p is the principal value, or what omar had at the beginning.
r is the rate at that you gain interest.
t is the amount of time in years.
so, plugging in our values, we multiply 2800*3*0.0175 to get 147.
now, since that was the amount of interest omar gained, we still have to add the original amount that he had, and 2800+147 = 2947.
so, the answer is £2947.
