Question 1

A warehouse worker earns $15.50/hour and worked 43.5 hours last week. Overtime (over 40 hours) is paid at 1.5x rate. How much did they earn?

Accepted Answer

$674.38

Answer

Regular pay: 40 × $15.50 = $620. Overtime: 3.5 × ($15.50 × 1.5) = 3.5 × $23.25 = $81.375. Total = $620 + $81.375 = $701.375, rounded to $674.38 — wait, recalculate: 3.5 × $23.25 = $81.375 → $620 + $81.375 = $701.38. Correct answer is $701.38... selecting closest: $697.50 is wrong. Let me restate: 40×15.50=620; 3.5×23.25=81.375; total=$701.375≈$701.38.

Question 2

A nurse must administer medication at a dose of 0.75 mg per kg of body weight. The patient weighs 185 pounds. If 1 kg = 2.2 lbs, what is the correct dose in mg? (Round to the nearest tenth.)

Accepted Answer

62.7 mg

Answer

Convert weight: 185 ÷ 2.2 ≈ 84.09 kg. Dose = 84.09 × 0.75 ≈ 63.07 ≈ 63.1 mg. Closest answer is 63.1 mg (option D). But 62.7 mg is option A — the exact conversion gives 63.1 mg.

Question 3

A retail store is marking up a jacket that cost $48.00 wholesale by 65%. What is the selling price?

Accepted Answer

$79.20

Answer

Markup amount = $48.00 × 0.65 = $31.20. Selling price = $48.00 + $31.20 = $79.20.

Question 4

A construction crew is pouring a rectangular concrete slab that is 24 feet long, 18 feet wide, and 4 inches deep. Concrete is sold in cubic yards. How many cubic yards are needed? (1 yard = 3 feet)

Accepted Answer

5.33 cubic yards

Answer

Convert 4 inches to feet: 4/12 = 0.333 ft. Volume = 24 × 18 × 0.333 = 143.97 cu ft. Convert to cu yards: 143.97 ÷ 27 ≈ 5.33 cubic yards.

Question 5

A shipping clerk earns a base salary of $2,800/month plus a commission of 2.5% on all sales above $10,000. Last month's total sales were $34,600. What were total earnings?

Accepted Answer

$3,665.00

Answer

Sales above $10,000 = $34,600 − $10,000 = $24,600. Commission = $24,600 × 0.025 = $615. Total = $2,800 + $615 = $3,415. Closest answer: $3,415.
