Solve it plz 29x < 38x + 18
storchak [24]

Answer:

x= -2

Step-by-step explanation:

The first thing I did was isolate the x's on one side.  I subtracted 38x from both sides.  This gives me:

-9x=18.  

Now i divide both sides by -9.  Giving me x=-2

interest rate of 2.99% compounded monthly for a 4 year loan, find the regular monthly payments required to repay the loan.
polet [3.4K]

Using it's formula, considering a loan of $10,000, the regular monthly payments required to pay off the loan will be of $221.3.

<h3>What is the monthly payment formula?</h3>

It is given by:

A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}

In which:

  • P is the initial amount.
  • r is the interest rate.
  • n is the number of payments.

In this problem, we have that the parameters are given as follows:

P = 10,000, r = 0.0299, n = 4 x 12 = 48.

Then:

r/12 = 0.0299/12 = 0.00249167.

Hence, the monthly payment will be given by:

A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}

A = 10000\frac{0.00249167(1+0.00249167)^{48}}{(1+0.00249167)^{48} - 1}

A = 221.3.

100%--------> 200 guests
