The cost of the mixture is $69 *$1 = $69. If all 69 pounds were peanuts, the cost would be 69*$0.99 = $68.31, which is $0.69 less. Each pound of walnuts used instead of peanuts adds $0.03 to the cost of the mixture, so there were $0.69/$0.03 = 23 pounds of walnuts. 
<span>_____ </span>
<span>Let w represent the number of pounds of walnuts in the mixture. Then 69-w is the number of pounds of peanuts. The cost of the mixture will be </span>
<span>1.02w + 0.99(69-w) = 1.00*69 dollars </span>
<span>0.03w + 68.31 = 69.00 </span>
<span>w = (69.00 - 68.31)/0.03 = 0.69/0.03 = 23</span>
        
             
        
        
        
Considering the withdraws and credits, Lucia's current available balance is of $65.53.
<h3>How do we find a balance?</h3>
It is given by the sum of the money that the people has with the pending credits, and subtracted by the pending withdraws.
In this problem, we have that:
- Lucia has $412.76, with pending credits of $134.00.
- She has pending withdraws of $481.23.
Hence, her avaiable balance is given by:
412.76 + 134 - 481.23 = $65.53.

Answer:

Step-by-step explanation:
for this case we have the following model for the cost of the car:

Where  is the initial amount on this case 17000, t the amount of years after the initial year and r the depreciation rate on this case:
 is the initial amount on this case 17000, t the amount of years after the initial year and r the depreciation rate on this case:

And for t =14 we can replace into the equation and we got:
