Investments: Complete the table if equal amounts are invested in each of two accounts paying 0.3% and 9% respectively, and the third account has twice as much as the first or second and is paying 5%, all are based on annual growth. Answer the question below?
Acct. Number Principal rate T I
7896-001 1
4645-002 1 0.09x
2345-003 1
a. If one year's combined interest income is $2200, how much was invested in each account. Form an equation and solve for the amount?

Re: help with a word problem...
you leave Gaylord heading south on I-75 at 67mph. A friend leaves Grayling on bicycle heading north on I-75 traveling at 8mph. If you both leave at the same time 1:00 pm. What time will you meet if the distance is 30 miles?

Re: help with a word problem...
Let x = number of hours each of you travel
If YOU are heading south at 67 mph, in x hours you'll travel 67*x miles
(that's because distance = rate * time)
Your friend travels north for the same amount of time, going 8 mph. The distance your friend travels is 8*x miles
Now...look at this diagram:
your distance friend's distance
*------------------------><------*
*---------------30 miles--------*
Do you see that the distance you traveled, PLUS the distance your friend traveled, must be the whole 30 miles between the two towns?
67x + 8x = 30
Solve that for x.....
