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. How much did Kirsten have originally? I tried working this so X was the original, 1/5*x was the gas, 1/5x *1/2 was for haircut and -7 for the lunch subtracting each to equal 13. 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. If $1 is invested at 5% it takes approximately 14.2 years to double. How many years will it take for $1 to double if invsted at 10%; and 12%? It asks to use the future value table or compound amount of $1.00.
-My answer for 10% would be 7.1 years since it is half of 14.2 but more than 5%? I have no idea what formula to use. Have no idea how I would even get these answered? What formula should be used if I have no idea of time?
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.
