Question 50196: I don't have alot but I always have trouble when it comes to word problems. Can you tell me if I have started correctly and if I have where I go from here. Thanks!! Andrea
The population of Cedar Rapids is expanding at a rate of P = P(sub0)e^kt,
where P(sub0) is the current population, k is the expansion rate and t is time (in years). If the populations were 10,000 in 1990 and 12,000 in 2000, when will it reach 20,000?
I have t= 2006 with P(sub0)=unknown
2000 is t-6=12,000
1990 is t-16=10,000.
Not sure where to go now.

Question 50206: This is what I have but when I worked it out it was inconceivable so I know I did something wrong. Please help. Andrea
Phil is making a Starbuck’s ® run for his exhausted Math 105 classes. He is going to buy a combination of Lattes and Cappuccinos. The Lattes cost $4 each and the Cappuccinos cost $3 each. If he needs 30 drinks total and has $100 to spend, how many of each should he buy?
Lattes - $4 each - Quantity is x - Total is 4x
Cappuccinos - $3 each - Quantity is 30-x - Total is 3(30-x) or 90-3x
Mixture - $100 to spend - Quantity is 30 - Total is 3000
So then I said 4x+90-3x=3000
x=2910
I think I have the right idea but obviously it doesn't work.

: I'm working on this coin problem and I can't seem to get the formula right for the equation. Here is what the problem gives as information:
A box currently contains 44 coins, consisting of pennies and dimes and quarters. the number of pennies is equal to the number of dimes, and the total value is $4.37. How may of each denominatin of coin does the box contain?
They have a table:
# of coins|deommination | value
x | .01 | .01x
_______________________________
x | |
_______________________________
| 0.25 |
|4.37 <-total
How do I formulate the equation from this world problem? (one i get the equation i can solve it but getting the equation is tricky).
