In Exercises \(1-8\), the principal \(P\) is borrowed at simple interest rater for a period of time t. Find the simple interest owed for the use of the money. Assume 360 days in a year. \(P=\$ 15,500, r=11 \%, t=90\) days
In Exercises 1-10, use $$ P M T=\frac{P\left(\frac{r}{n}\right)}{\left[1-\left(1+\frac{r}{n}\right)^{-n t}\right]} $$ to determine the regular payment amount, rounded to the nearest dollar. In terms of paying less in interest, which is more economical for a \(\$ 150,000\) mortgage: a 30 -year fixed-rate at \(8 \%\) or a 20 -year fixed-rate at \(7.5 \%\) ? How much is saved in interest?
a married couple filing jointly with a taxable income of \(\$ 250,000\) and a \(\$ 7500\) tax credit
You decide to work part-time at a local supermarket. The job pays \(\$ 16.50\) per hour and you work 20 hours per week. Your employer withholds \(10 \%\) of your gross pay for federal taxes, \(7.65 \%\) for FICA taxes, and \(3 \%\) for state taxes. a. What is your weekly gross pay? b. How much is withheld per week for federal taxes? c. How much is withheld per week for FICA taxes? d. How much is withheld per week for state taxes? e. What is your weekly net pay? f. What percentage of your gross pay is with held for taxes? Round to the nearest tenth of a percent.
Suppose that you have \(\$ 12,000\) to invest. Which investment yields the greater return over three years: \(7 \%\) compounded monthly or \(6.85 \%\) compounded continuously?
