Question

Gordon rosel went to his bank to find out how long it will take for $900 to amount to $1,090 at 9% simple interest. calculate the number of year

Answer 1

Alright, so I=prt. I is 1090-900=190=interest.  It starts at 900, so that is p. R is 0.09. 1090=900*0.09*t, so 1090/(900*0.09)=t=around 13 years
