Question 2

Solve.
-Suppose that you own a home which is valued at $\$ 153,000$. You must move to a different city. Use the formula below to find out how much it would cost to buy a similar (replacement) home in the city that you will move to. Assume that the index of your city is 207 and that the index of the new city is 137. Round your answer to the nearest dollar.
Cost of Your Home in New City $=$(Value of Your Home $) \div$ (Index of Your City) $\times$ (Index of New City)
A) $\$ 101,261$
B) $\$ 231,175$
C) $\$ 106,761$
D) $\$ 223,575$

Accepted Answer

The cost of the home in the new city is calculated as $(\$153,000 \div 207) \times 137 = \$101,260.869$, which rounds to $\$101,261$.

Question 3

Solve.
-A car rental company charges $\$ 22$ per day and $\$ 0.35$ per mile to rent a car. What is the total bill if a car is rented for 3 days and is driven 148 miles?
A) $\$ 3307.8$
B) $\$ 67.05$
C) $\$ 117.80$
D) $\$ 14.20$

Accepted Answer

The total bill is calculated by adding the daily charge and the mileage charge: $3 \times 22 + 148 \times 0.35 = 66 + 51.80 = 117.80$.

Question 4

Solve.
-BT&T charges $0.31 for the first minute and $0.28 for each additional minute for a long-distance call. How much will a 30 minute long-distance call cost?
A) $\$ 8.71$
B) $\$ 8.40$
C) $\$ 8.43$
D) $\$ 9.30$

Accepted Answer

The first minute costs $0.31, and the remaining 29 minutes each cost $0.28. So, the total cost is $0.31 + (29 * $0.28) = $0.31 + $8.12 = $8.43.

Question 6

Solve.
-In order to buy a $\$ 20,000$ car, you put down $\$ 2500$ and take out a loan on the balance. To pay off the loan, you pay $\$ 359.72$ per month for the following 72 months. How much more will you end up paying for the car than the original price of $\$ 20,000$ ? Round your answer to the nearest dollar.
A) $\$ 28,400.00$
B) $\$ 5900.00$
C) $\$ 25,900.00$
D) $\$ 8400.00$

Accepted Answer

The total amount paid for the car is the down payment plus the total of all monthly payments: $\$2500 + (72 \times \$359.72) = \$25,900$. The difference between this total and the original price of the car is $\$25,900 - \$20,000 = \$5,900$. However, the question asks for how much more this total payment is compared to the original price, which has been calculated but the correct interpretation of the total amount paid over the original price is actually the sum of payments made, which includes the interest over the original price, leading to a misunderstanding in the explanation provided. The correct calculation for the total amount paid is indeed \$25,900, but the question specifically asks for how much more will be paid than the original price, which is the difference between the total amount paid and the original price, correctly calculated as \$5,900 but incorrectly matched with the choices due to a misinterpretation in the explanation process. The correct approach to find how much more was paid involves calculating the total amount paid over the loan period and subtracting the car's original price, which was initially correctly calculated but then led to a confusion in matching the answer. The total payments made over the loan period amount to \$25,900 (down payment + loan payments), and subtracting the original price of the car (\$20,000) from this total gives the correct answer of how much more was paid than the original price, which is \$5,900, indicating a mistake in the final matching of the answer choice due to a misinterpretation of the question's requirement.

Question 7

Solve.
-In Antarctica, the high temperatures for the last four days have been $17.2^{\circ}, 5.6^{\circ}, 6.2^{\circ}$, and $10.3^{\circ}$. What is the average high temperature for this four-day period?
A) $9.225^{\circ}$
B) $9.825^{\circ}$
C) $7.845^{\circ}$
