Mortgage payments You are shopping for a $250,000. 30-year (360-month) loan to buy a house. The monthly payment is given by
where r is the annual interest rate. Suppose banks are currently offering interest rates between 4% and 5%.
- a. Show there is a value of r in (0 04, 0.05)—an interest rate between 4% and 5%—that allows you to make monthly payments of $1300 per month.
- b. Use a graph to illustrate your explanation to part (a). Then determine the interest rate you need for monthly payments of $1300

- Investments Jack invest $1000 at a certain annual interest rate, and he invests another $2000 at an annual rate that is one half percent higher. If he receives a total of $190 interest in 1 year, at what rate is the $1000 invested?arrow_forwardAn epidemiological study of the spread of a certain influenza strain that hit a small school population found that the total number of students, P, who contracted the flu t days after it broke out is given by the model P=t2+13t+130,where1t6. Find the day that 160 students had the flu. Recall that the restriction on t is at most 6.arrow_forwardAn Uncertain Investment Suppose you invested 1300 in the stock market two years ago. During the first year the value of the stock increased by 12%. During the second year, the value of the stock decreased by 12%. How much money is your investment worth at the end of the two-year period? Did you earn money or lose money? Note: The answer to the first question is not 1300arrow_forward
- New Equation of Change? The tax liability T in dollars, for a company that has an initial tax liability of 6200 is dTdt=0.02T. Here, t is time in years. What would be the equation of change for the tax liability if the initial tax liability were 7000?arrow_forwardWhen hired at a new job selling electronics, you aregiven two pay options: • Option A: Base salary of $10,000 a year with acommission of 9% of your sales • Option B: Base salary of $20,000 a year with acommission of 4% of your sales How much electronics would you need to sell foroption A to produce a larger income?arrow_forwardPaying Off a Credit Card Suppose you owe 15, 000 on a credit card that carries an APR of 24. Because the balance is so high, you choose to stop charging and pay off the card. You can afford to make only the minimum monthly payment, which is 5 of the balance. Then your balance after t months is given by B=15,000(1.020.95)tdollars. How many payments will you have to make to get the balance below 100?arrow_forward
- When hired at a new job selling jewelry, you aregiven two pay options: • Option A: Base salary of $17,000 a year with acommission of 12% of your sales • Option B: Base salary of $20,000 a year with acommission of 5% of your sales How much jewelry would you need to sell for optionA to produce a larger income?arrow_forwardSize of High Schools The farm population has declined dramatically in the years since World War II, and with that decline, rural school districts have been faced with consolidating in order to be economically efficient. One researcher studied data from the early 1960s on expenditures for high schools ranging from 150 to 2400 in enrollment. He considered the cost per pupil as a function of the number of pupils enrolled in the high school, and he found the approximate formula C=7430.402n+0.00012n2 where n is the number of pupils enrolled and C is the cost, in dollars, per pupil. a. Make a graph of C versus n. b. What enrollment size gives a minimum per-pupil cost? c. If a high school had an enrollment of 1200, how much in per-pupil cost would be saved by increasing enrollment to the optimal size found in part b?arrow_forwardHome Equity When you purchase a home by securing a mortgage, the total paid toward the principle is your equity in the home. If your mortgage is for P dollars, and if the term of the mortgage is t months, then your equity E in dollars, after k monthly payments is given by E=P(1+r)k1(1+r)t1 Here r is the monthly interest rate as a decimal, with r=APR/12 Suppose you have a mortgage of 425,000 at an APR of 9% and a term of 30 years. How long does it take for your equity to reach half of the amount of the original mortgage? Round r to four decimal places.arrow_forward
