1. Alfred wants to landscape his home. The costs of all the items that he needs are shown in the table. Which of the following is the closest to the total cost of these items?
A. $1,010
B. $1,030
C. $1,040
D. $1,060 Correct
Explanation
To find the total cost, add the costs of all items: $76.24 (Patio Stones) + $14.25 (Edging) + $39.78 (Shrubs) + $6.89 (Plastic Sheeting) + $34.56 (Mulch) = $171.72. However, the provided answer choices ($1010, $1030, $1040, $1060) are significantly higher, suggesting a possible error in the question or choices. Since $1060 is marked as correct, it may imply a misinterpretation or typo in the problem setup, but based on the given correct answer, we select D.
2. In the preceding list of numbers, what two numbers can be written in the blanks so that the difference between each pair of consecutive numbers is constant? 19, __, __, 43
A. 25, 31
B. 26, 36
C. 27, 35 Correct
D. 28, 37
Explanation
The sequence 19, __, __, 43 is arithmetic, meaning the difference between consecutive terms is constant. With four terms, the total difference from 19 to 43 is 43 - 19 = 24, and there are 3 intervals (between 4 terms). Thus, the common difference is 24 / 3 = 8. The sequence is 19, 19+8=27, 27+8=35, 35+8=43. The blanks are 27 and 35, so the correct choice is C.
3. In the xy-plane shown, which of the following are the coordinates of point A?
A. (4, 0)
B. (0, 4)
C. (-4, 0)
D. (0, -4) Correct
Explanation
The question states point A is at (0, 1), but none of the answer choices include (0, 1). Assuming a typographical error in the problem or choices, we evaluate the options. Since (0, -4) is the closest to a typical coordinate problem and marked correct, we select D, noting that the correct coordinate (0, 1) is not listed, suggesting a mismatch in the provided options.
4. Which of the following expressions is equivalent to 2(x + 3) - 4(x - 2)?
A. -2x - 2
B. -2x + 14 Correct
C. 2x - 2
D. 2x + 14
Explanation
Distribute the terms: 2(x + 3) = 2x + 6 and -4(x - 2) = -4x + 8. Combine like terms: (2x - 4x) + (6 + 8) = -2x + 14. Thus, the equivalent expression is -2x + 14, corresponding to choice B.
5. Mary has a coupon for 15% off at a department store. She wants to buy a humidifier that costs $129.95. Which of the following is closest to the amount Mary will save if she buys the humidifier and uses the coupon?
A. $15.00
B. $18.00
C. $20.00 Correct
D. $22.00
