5000 x 0.06 = 300
300 x 10 = 3000

It was eight years.
42 x 8 x 3.5 ie 1176
1282.5
Simple interest, 500 + (5 x 5 x 4) = 600. Compound 500 x 1.04^5 = 632.66

She will have to wait 4 years.
450*8/100*2 = 72

It will grow to nine eighths of the original sum.
9% of 1000 is 9*1000/100 = 90. Since it is simple interest, it generates earnings of 90 each year, or 270 in 3 years.
Simple interest = money invested x rate/100 x number of years
