With $3500 each, Martin and Edward opened separate accounts. Each account offered 4.5% interest over 10 years. At the end of 10
years, Edward earned more than Martin. Why? A. Edward invested for a different amount of time than Martin. B. Edward had a different interest rate than Martin. C. Edward earned compound interest, and Martin earned simple interest. D. Edward e Soomeone helpppp meeee
Given that Edward and Martin invested the same amount of $3500, with interest rate of 4.5% and time period of 10 years: The difference in the amount of money will be brought about by different schemes in which they both invested the money. The interest earned from above cash under simple interest will be: S.I=(PRT)/100 S.I=3500*4.5/100*10=$1575 the total amount after 10 years will therefore be: 1575+3500 =$5075
The same amount if it was compounded annually, the amount after 10 years will be: FV=P(1+r/100)^n FV=3500(1+3.5/100)^10 FV=4,937.10 we therefore conclude that the answer is: Edward must have earned simple interest while Martin earned compound interest.
Πr²h=175 πr²*7=175 Divide both sides by 7 πr²=25 Divide both sides by π (3.14) r²=7.96 Square root of 7.96=2.82 r=2.82 Diameter is 2r. 2.82*2 2.82*2=5.64
