Q1A store marks up a wholesale price of $40 by 25%. What is the final retail price?
Show answer
✓ Correct answer: $50.00
A 25% markup on $40 equals $40 × 1.25 = $50.00; markup means multiplying the original price by (1 + rate).
Q2On a number line, which integer is closest to −7.8?
Show answer
✓ Correct answer: −8
−7.8 lies between −8 and −7, and since |−7.8 − (−8)| = 0.2 while |−7.8 − (−7)| = 0.8, the nearest integer is −8.
Q3A recipe calls for 2¾ cups of flour. If you want to make 1½ times the recipe, how many cups of flour do you need?
Show answer
✓ Correct answer: 4⅛ cups
Converting to improper fractions: (11/4) × (3/2) = 33/8 = 4⅛ cups; multiplying mixed numbers requires converting to improper fractions first.
Q4Which of the following is equivalent to 3⁻²?
Show answer
✓ Correct answer: 1/9
A negative exponent denotes the reciprocal of the base raised to the positive exponent: 3⁻² = 1/3² = 1/9.
Q5A car travels 180 miles on 6 gallons of fuel. At the same rate, how many gallons are needed for a 255-mile trip?
Show answer
✓ Correct answer: 8.5 gallons
The unit rate is 180 ÷ 6 = 30 miles per gallon; dividing 255 by 30 gives 8.5 gallons, using the proportional relationship distance = rate × gallons.
Q6Solve for x: 4(x − 3) + 2x = 18
Show answer
✓ Correct answer: x = 5
Distributing gives 4x − 12 + 2x = 18, so 6x = 30, yielding x = 5; check: 4(5−3) + 2(5) = 8 + 10 = 18 ✓.
