Determine the cost of the points and the new interest rate for each loan amount and interest rate. Assume each point costs 1% of the loan amount. $550,000, original APR 4.75%, 1 point with a 0.3% discount.

For the following exercise,

Determine the value of the annuity for the indicated monthly deposit amount, the number of deposits, and the interest rate.

Deposit amount: $\$ 100$; total deposits: $120$ ; interest rate: $10 \%$, compounded semi-annually

Find the simple interest paid to the nearest cent for each loan amount, interest rate, and time. $1,000, 7%, 2 years

Suppose that $10,000 is invested at continuous rate r and grows to$17,160 in 9 years. Find the interest rate r.

Use the compound interest formula, $A(t)=P\left(1+\frac{r}{n}\right)^{n t}$.

Use properties of rational exponents to solve the compound interest formula for the interest rate, $r$.

Bill Rich signed a 180-day note for $1,250. He repaid the loan when due with interest at an annual rate of 12 % using a banker's year.

Tony Colito paid$19.50 in interest on a loan of $2,600 for 1 month. What rate of interest did he pay?

Suppose you deposit m dollars at the beginning of every month in a savings account that earns a monthly interest rate of r, which is the annual interest rate divided by 12 (for example, if the annual interest rate is 2.4%, r=0.024/12=0.002). For an initial investment of m dollars, the amount of money in your account at the beginning of the second month is the sum of your second deposit and your initial deposit plus interest, or m+n(1+r). Continuing in this fashion, it can be shown that the amount of money in your account after n months is $A_{n}=m+m(1+r)+\cdots+m(1+r)^{n-1}$. Use geometric sums to determine the amount of money in your savings account after 5 years (60 months) using the given monthly deposit and interest rate. Monthly deposits of $250 at a monthly interest rate of 0.2%
