Question 212295: Kirsten spent 1/5 of her money for gasoline. Then she spent 1/2 of what she had left for a haircut. She bought lunch for $7. When she got home she had $13 left.

But I don't think its right. Maybe work it backwards with 13+7=20 then what to do with the haircut and gas?

Question 213270: 1.Interest rate is critical to the speed at which your investment grows. If $1 is invested at 2%, it takes approximately 34.9 years to double.

It asks to use the future value table or compound amount of $1.00.

2. At what interest rate would you need to invest to have your money double in 10 years? same it asks to use the table and use the 10 year row that represents doubling? I'm lost!

Question 215071: I'm having trouble setting up this question, help would be appreciated:
Research has shown that if 100 pear trees are planted, then the annual revenue is $90 per tree. If more trees are planted they have less room to grow and generate fewer pears per tree. As a result, the annual revenue per free is reduced $0.70 for each additional tree planted. No matter how many trees are plated, the cost of maintaining each tree is $7.40 per year. How many pear trees should be planted to maximize the profit from the orchard for one year?
Let 'x' represent the amount of pear trees planted.
Profit = Revenue - Cost
Revenue = (90-0.7x)(100+x)
Cost = 7.40(100+x)
Profit = 9000+90x-70x-0.7x^2-740+7.4x
The function I work out is:

However I can't work it out correctly, can someone help me set this problem up?? Thanks in advance.
