Question 209325: Please help me with the following word problem, I do not know how to do the percentages.. and I can not figure out the answer. thank you so much
Nancy had $18,000 in savings. She invested part of it at 7.5% interest and the rest at 9%. If the total income from the two investments was $1560, how much did she invest at 9%? Type in your numerical answer only (in dollars)
Answer by checkley77(12844)   (Show Source):
You can put this solution on YOUR website! .09X+.075(18,000-X)=1,560
.09X+1,350-.075X=1,560
.015X=1,560-1,350
.015X=210
X=210/.015
X=$14,000 INVESTED @ 9%.
18,000-14,000=$4,000 INVESTED @ 7.5%
PROOF:
.09*14,000+.075*4,000=1,560
1,260+300=1,560
1,560=1,560
