If we call y the height of the plane, we know when the time (x) is 0, the height is 30000. So let's write that in:

y = 30000 + (0)

Then, for every increase of a minute (x increases by 1), the height reduces by 2000. This can be written as:

y = 30000 - 2000x

Using what we know about y = mx+c equations, the slope of the line is -2000, and the y-intercept is (0, 30000).

Wade Ellis buys a new car for $16,183.11. He puts 10% down and obtains a simple interest amortized loan for the rest at 11 1/2%
oksano4ka [1.4K]

Answer:

If a new car was purchased for a cost of $16,183.11, and a down payment of 10% of the value was made, the initial payment was $1,618.31.

Thus, the remaining amount to be financed is $14,564.79. It will be financed in 4 years, at an annual interest rate of 11.5%, for four years. Thus, the total interest will be 46% (11.5 x 4), to be distributed among the 4 years of the financing. Then, the total amount to be paid will be $21,264.59, which will be paid in 48 equal monthly payments of $443.01 (21,264.59 / 48).
