rationales are highlighted in green.
Mathematical Reasoning
1. A store is offering a 20% discount on a jacket originally priced at $85. What is the final
sale price before tax?
A) $17.00
B) $65.00
C) $68.00
D) $70.00
Rationale: 20% of $85 is 0.20 × 85 = $17. Subtracting the discount from the original price:
$85 - $17 = $68.00.
2. Solve for x: 3x - 7 = 14.
A) 5
B) 7
C) 8
D) 21
Rationale: Add 7 to both sides: 3x = 21. Divide by 3: x = 7.
3. What is the area of a rectangle with a length of 12 cm and a width of 5 cm?
A) 34 cm²
B) 17 cm²
C) 50 cm²
D) 60 cm²
Rationale: Area = length × width = 12 cm × 5 cm = 60 cm².
4. Which of the following fractions is equivalent to 3/4?
A) 9/12
B) 6/10
, C) 12/20
D) 15/16
Rationale: Multiplying numerator and denominator of 3/4 by 3 yields 9/12.
5. A line passes through points (2, 3) and (4, 7). What is the slope of the line?
A) 1
B) 2
C) 1/2
D) 4
Rationale: Slope m = (y2 - y1) / (x2 - x1) = (7 - 3) / (4 - 2) = = 2.
6. Simplify the expression: 4(2x - 3) + 5.
A) 8x - 12
B) 8x + 2
C) 8x - 7
D) 8x - 2
Rationale: Distribute 4: 8x - 12 + 5 = 8x - 7.
7. If a car travels at an average speed of 60 miles per hour, how far will it travel in 2.5
hours?
A) 120 miles
B) 140 miles
C) 160 miles
D) 150 miles
Rationale: Distance = speed × time = 60 × 2.5 = 150 miles.
8. What is the value of 5³ - 4²?
A) 109
B) 117
C) 121
D) 99
Rationale: 5³ = 125, 4² = 16. 125 - 16 = 109.
9. What is the perimeter of a square whose side length is 9 inches?
A) 18 inches
