Hey there
That's easy
Divide 2750 by 40 and a good estimate would be 68 dollars
Hope this helps
Principal P = $500, Rate = 3 % = 3/100 = 0.03 would assume per year,
Time t = 6 months = (6/12) year = 0.5 year.
Simple Interest, I = P*r*t
= 500*0.03*0.5 = 7.5
And so therefore your answer is 7.5
1/2 ÷ -3/7 = -7/6 The answer is -7/6
