Is this Correct?
yup, they are all right.
Good job.
1. The correct series of keys Jane should press on her calculator is option (C). She starts with her current balance of $68.00 (use the ON/C button to clear the calculator), then adds her deposit of $75.00 by pressing "+ 7 5 =", which gives her a new balance of $143.00. Then she subtracts the two checks she wrote by pressing "- 5 - 6 2 . 5 0 =", which gives her a final balance of $75.50.
2. The correct series of keys Lorenzo should press on his calculator is option (D). He starts with his current balance of $118.00, then subtracts his two checks by pressing "- 9 - 8 4 . 2 5 =", which gives him a balance of $24.75. Finally, he adds his deposit of $95.00 by pressing "+ 9 5 =", which gives him a final balance of $119.75.
3. To find Ray Cupple's total cost, you start with the cost of the basic car ($10,150.00) and add the cost of the options ($738.00). Then you add the 6% sales tax and the license and registration fee ($50.00). The correct option is (B), which gives a total cost of $11,591.28.
4. To find John Gray's total cost, you start with the cost of the basic car ($8,250.00) and add the cost of the options ($324.00). Then you add the 6% sales tax and the license and registration fee ($50.00). The correct option is (D), which gives a total cost of $9,138.44.
5. To calculate the profit or loss from selling the stock, you need to find the difference between the selling price and the buying price, and then multiply that by the number of shares. The stock was bought at 20 1/4 and sold at 25 1/4, which gives a difference of 5. The correct option is (C), which states that you'll make a profit of $150 (5 * 30 shares).
6. Using the same profit/loss calculation as in the previous question, the stock was bought at 31 1/2 and sold at 35 1/4, which gives a difference of 3 3/4. The correct option is (A), which states that you made a profit of $75 (3.75 * 20 shares).
7. To find the value of the car in three years after a depreciation of 48%, you multiply the original price ($11,400.00) by 0.52 (100% - 48%). The correct option is (B), which gives a value of $5,928.00.
