Answer:
3.5
Step-by-step explanation:
If x is the volume of 10% solution, and y is the volume of 6% solution, then:
x + 7 = y
0.10x + 0.04(7) = 0.06y
Solve the system of equations.
0.10x + 0.04(7) = 0.06(x + 7)
0.10x + 0.28 = 0.06x + 0.42
0.04x = 0.14
x = 3.5
3.5 liters of 10% solution is needed.
2x+5=5x-25
Subtract 2x from both sides
Add 25 to both sides
30=3x
Then replace x with 10
2(10)+5 =25
25 times 2 =50
Answer:
Ashley would have to pay an additional $608.52 in interest when the length of the loan changes from 3 years to 5 years.
Step-by-step explanation:
Although the problem gives us the initial amount of the balance ($4000) and the interest rate (13%), we are really only concerned with the total amount Ashley will make in payments in three years versus five years. If she pays $134.78 for three years, that is 36 months, or $134.78 times 36 which is equal to $4852.08. However, if she decides to take longer to pay it and instead pays $91.01 for five years, or 60 months, then her total amount paid would be $5460.60. To find the difference between these two, simply subtract $5460.60-$4852.08 to get $608.52.
