Your friend already has $50 saved in an account, and he decides to add another $10 each month.?
Write an equation for the amount of money, y, after x months.
回答 (4)
y=50+10x where x refers to month (1,2,3,...)
What's the interest rate on the account? Assuming there is no interest earned, it would just be the $50 plus an additional $10 for every month that the account has been open.
y = 50 + 10x
The standard form of a line is y = mx + b, so let's flip that around.
Answer:
y = 10x + 50
