Answer:
$38
Step-by-step explanation:
If there are three adults (or not-students) then that amounts to $30
(10*3)
Since they all go in one car they only pay $8
Add them all together!
Answer:
x=amount invested at 7%
2x=amount invested at 8%
3x=amount invested at 9%
interest=principal*rate*time (time=1 year)
$150=0.07x+0.08*2x+0.09*3x
$150=0.07x+0.16x+0.27x
$150=0.50x
$1500=5x
x=$300 invested at 7%
2x=$600 invested at 8%
3x=$900 invested at 9%
