Hej satellite help me please....

2. satellite73 Group Title

sorry it should be $.07x+.09(19000-x)=1590$

3. satellite73 Group Title

i get x = 6000

4. Sariah Group Title

C'mon one question per thread

6. Hero Group Title

I wanted to discuss the first question

7. Sariah Group Title

What do you think Hero?

8. Hero Group Title

Satellite, did you set that up as two equations then substitute y into the first one?

9. Hero Group Title

.07x + .09y = 1590 x + y = 19000

10. Hero Group Title

?

11. Sariah Group Title

Hero the right answer is not D_= 6000 in bonds, is it?

12. satellite73 Group Title

no i reasoned as follows. put x = amount in 7% CD, then since the total is 19000 the rest must be 19000 - x

13. Hero Group Title

But the equation comes out in the same manner as what you posted

14. satellite73 Group Title

yes of course. i put x = amount in 7% and got x = 6000 so that is the amount in municipal bonds. the rest is in the 9% stuff

15. Hero Group Title

What does x and y represent?

16. satellite73 Group Title

i guess i just did the y = 19000 - x part in my head

17. Hero Group Title

I'm thinking x is the amount invested in bonds and y is the amount invested in certificates, right?

18. Hero Group Title

I mean, the answer must be d

19. Sariah Group Title

Ok the same i think...
