document.write( "Question 498977: You have $1000 to start a retirement account. The 1st month, you deposit $1000, plus your new monthly deposit amount of $150. Then every month you deposit the $150 in a retirement account earning 3.8% interest compounded monthly. If there are 20 years until you retire, how much will you have? How much will you have if you retire in 30 years? \n" ); document.write( "
