From equations (1) & (2), we find:
6x - 8 = - 3x +10
Plug x = 2 in equation (1)
y = 6(2)-8 = 12-8 =4
So,

Answer: ok what is it
Step-by-step explanation:
<u>Answer:</u>
Total paid = $717.3
Finance charge = $167.3
<u>Step-by-step explanation:</u>
The cost price of mountain bike = $550
The down payment on bike = 75% of $550 = 0.75 * 550 = $412.5
We know that he will make 12 payments of $25.40 each so total monthly payments = 12 * 25.40 = $304.8
The total amount paid = Down payment + Total monthly payments = $412.5 + $304.8 = $717.3
The finance charge = Total amount paid - Cost price = $717.3 - $550 = $167.3
You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.
Hope this helps !
