it's 20000-x

Yeah sorry that.

.08x = interest earned on 8% investment .095(20000-x)= interest earned on 9.5% investment

Total interest earned is $1675 Write and solve the equation that says the sum of the two interest amounts is1675
calculusxy
  • calculusxy
.08x + .095(20000-x) = $1675
Mertsj
  • Mertsj
Solve it.
calculusxy
  • calculusxy
0.08x + 0.095(20000-x) = 1675 0.08x + 1900 + 0.095x = 1675 0.175x + 1900 = 1675 0.175x = -375 2142?

-.095x

  • calculusxy
For what? Why is it negative?
Mertsj
  • Mertsj
\[.095(20000-x)=1900-.095x\]
calculusxy
  • calculusxy
oh yeah

0.705x = 1675 x = 2375
Mertsj
  • Mertsj
\[.08x+.095(20000-x)=1675\] \[.08x+1900-.095x=1675\] \[-.015x+1900=1675\] \[-.015x=-225\] \[\frac{-.015x}{-.015}=\frac{-225}{-.015}\] \[x=15000\]

I am sorry. I am really tired so I can't focus as usual. I have to get it on track. :)

So 15000 was invested at 8% 20000-x=5000 = amount invested at 9.5%
calculusxy
  • calculusxy
x= 15000
