Question 208034: Suppose you are offered two jobs. One pays $30,000 the first year with annual raises of $2000 each year. The second offers a starting salary of $27,000 and raises of 8% each year. At the end of ten years, what would your yearly salary be from a) the first job? b)the second job?
My answer; $30,000=1 year + $2000=each coming year * 10 years
but since the first year is already given I dont have to count it with do I? (thats why I am not sure if I got this right)
a) 2000*9=18,000 30,000+18,000=48,000 so $48,000 after 10 years
b)27,000=1 year + 8% each coming year * 10 years
(here again I only put 9 years to count, since 27,000 already is the first year, or is that wrong?)
270*8=2,160 2,160*9=19,440 27,000+19,440=46,440 so $46,440 after 10 years
Could someone please tell me if I solved the problem right?
