Susan invests

Mathematics

Arturiano [62]3 years ago
5 0
Let f=amount invested at 4% and e=amount invested at 8%

0.04f+.08e=800

However, e=2f so the above equation becomes:

0.04f+0.08(2f)=800

0.04f+0.16f=800

0.2f=800

f=$4000, since e=2f

e=$8000

So Susan invested $4000 at 4% and $8000 at 8%.

Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):

265 + 48h = 553

Substract both sides by 265:

48h = 288

Divide:

h = 6
