In an installment loan, a lender loans a borrower a principal amount P, on which the borrower will pay a yearly interest rate of i (as a fraction, e.g. a rate of 6% would correspond to i=0.06) for n years. The borrower pays a fixed amount M to the lender q times per year. At the end of the n years, the last payment by the borrower pays off the loan.

After k payments, the amount A still owed is

<span>A = P(1+[i/q])k - Mq([1+(i/q)]k-1)/i, = (P-Mq/i)(1+[i/q])k + Mq/i. </span>The amount of the fixed payment is determined by<span>M = Pi/[q(1-[1+(i/q)]-nq)]. </span>The amount of principal that can be paid off in n years is<span>P = M(1-[1+(i/q)]-nq)q/i. </span>The number of years needed to pay off the loan isn = -log(1-[Pi/(Mq)])/(q log[1+(i/q)]). The total amount paid by the borrower is Mnq, and the total amount of interest paid is<span>I = Mnq - P.</span>

Plase help me I already set the equation up I just need you to solve it.
masya89 [10]

\sf \frac{6}{30}  =  \frac{x}{100}

Solve for x by cross multiplication

\sf6 \times 100 = x \times 30

  • Multiply the numbers

\sf \: 600 = 30x

  • Swap the sides of equation

\sf \: 30x = 600

  • Divide both sides of equation by 30

\boxed{ \tt \: x = 20}
