We need to solve the word problem using two equations, and I can never get the second equation right. Here's what I get:
x=Sam's age Y= Tony's age
x+10=y
5+y=2x

Question 436853: I have an investment of $1500. After 4 years, it becomes $1700. The number of compounding periods are 360. What is my rate?
I do not know how to go from my last step and find an answer.
This is what I have so far, but do not know how to go from here. It is very confusing to me.
1700=1500(1+ r/360)^360 x 4
1700=1500(1+ r/360)^1280
ln(1+r/360)^1280=ln(17/15)
1280ln(1+r/360)=ln(17/15)
ln(1+r/360)=ln(17/15) all over 1280
=1/1280ln(17/15)
=ln(17/15)^1/1280
r=360[((17/15)^1/1280)-1]
This is where I do not understand how to go. I have tried to divide 17 by 15 giving me 1.13, then taking that to the power of 1/1280, giving me 8.9, then subtracting 1, which gives me a -.9991145833.

145.90 - .05=x

Question 439617: Debbie, an outside saleswoman, uses her car for both business and pleasure. Last year, she traveled 30,000 miles, using 900 gallons of gasoline. Her car gets 40 miles per gallon on the highway and 25 in the city. She can deduct all highway travel, but no city travel, on her taxes. How many miles should Debbie be allowed as a business expense?
I set my equation up as 40x + 25(30000 - x) = 30000(900), but this isn't right because the answer is too large. I tried also 40x + 25x = 900 but do not know how to factor in the 30,000 miles. Could you explain to me step by step how to solve this problem, and how and why the equation to be solved is set up the way that it is?
