If there are 4 trucks then the first truck weighs x
then x+2tons
then x+4tons
then x+6tons = 32tons
so 4x+12=32
-12 -12
/4 /4
x=5
so plug it back in
truck 1= 5tons or 10,000lbs
truck 2= 7tons or 14,000lbs
truck 3= 9tons or 18,000lbs
truck 4= 11tons or 22,000lbs

The solutions are
- it is going to take 15.9 months to raise 10000 dollars
- You will have $37.31 after you have bought the car
- The money deficit would be $37.31
<h3>How to solve the question</h3>
a. 10000 = 9359.08e(0.05)
e⁰⁰⁵ = 10000/9359.08
= 0.05 = ln(10000/9359.08)
= 1.325 years
convert to months = 15.9 months
Hence it is going to take 15.9 months to raise 10000 dollars
b. 9359.08 x e^(0.05 x1.25)
= 9962.69
10000 - 9962.69
= $37.31
You will have $37.31 after you have bought the car
c. The money loss and the deficit would be same as above $37.31
d. ln(e^a) = a
We can clearly see that the money cannot be raised in the 15 months from $ 9359.08. there is a deficit amount of $37.31

Answer:
Step-by-step explanation:
For mixture problems, it is convenient to define a variable to represent the amount of the greatest contributor. Let x represent the amount of 22% solution in the mix. Then 4.8-x is the amount of 10% solution.
The amount of alcohol in the mix is ...
0.22x +0.10(4.8-x) = 0.12(4.8)
Eliminating parentheses, we have ...
0.22x -0.10x +0.10(4.8) = 0.12(4.8)
Subtracting (0.10)(4.8) and combining x-terms gives ...
0.12x = 0.02(4.8)
x = (0.02/0.12)(4.8) = 0.8 . . . . . divide by the x-coefficient
The scientist needs 0.8 L of 22% solution and 4.0 L of 10% solution.
