  1. A manufacturing plant produces 1,200 units in 8 hours with 6 workers. At the same rate, how many units can 9 workers produce in 10 hours?

    Answer: 2,250 units

    Rate per worker per hour = 1,200 ÷ (8 × 6) = 1,200 ÷ 48 = 25 units. New output = 25 × 9 × 10 = 2,250 units.

  2. A retail manager reviews the following weekly sales data: Mon $3,200 | Tue $2,850 | Wed $4,100 | Thu $3,650 | Fri $5,400 | Sat $6,200. What is the average daily sales, and on how many days did sales exceed the average?

    Answer: Average $4,233 — 3 days above

    Total = 3,200+2,850+4,100+3,650+5,400+6,200 = 25,400. Average = 25,400÷6 ≈ $4,233. Days above: Wed $4,100 (no), Thu $3,650 (no), Fri $5,400 (yes), Sat $6,200 (yes), and Mon/Tue are below. Actually: only Fri and Sat exceed $4,233 — that is 2 days. Let me recount: $5,400 > $4,233 ✓, $6,200 > $4,233 ✓ = 2 days. Correct answer is option B.

  3. A warehouse has a rectangular storage area 60 feet long and 40 feet wide. Pallets occupy 25% of the floor space. Each pallet measures 4 feet × 4 feet. How many pallets fit in the storage area?

    Answer: 150 pallets

    Total area = 60 × 40 = 2,400 sq ft. Pallet area = 2,400 × 0.25 = 600 sq ft. Each pallet = 4 × 4 = 16 sq ft. Pallets = 600 ÷ 16 = 37.5 → 37 pallets.

  4. A nurse needs to mix a 30% saline solution using a 10% saline solution and a 50% saline solution. How many mL of the 10% solution are needed to make 400 mL of the 30% solution?

    Answer: 200 mL

    Let x = mL of 10% solution. Then (400−x) = mL of 50% solution. Equation: 0.10x + 0.50(400−x) = 0.30(400). 0.10x + 200 − 0.50x = 120. −0.40x = −80. x = 200 mL.

  5. A restaurant orders produce weekly. The produce cost per week for the past 5 weeks was: $1,240 | $980 | $1,380 | $1,150 | $1,470. What is the median weekly cost?

    Answer: $1,240

    Sort the values: $980, $1,150, $1,240, $1,380, $1,470. The median (middle value of 5) is $1,240.

  6. A construction crew can complete a road project in 12 days if 8 workers are assigned. The project deadline requires it to be finished in 8 days. How many workers are needed?

    Answer: 12 workers

    Total work = 8 workers × 12 days = 96 worker-days. Workers needed = 96 ÷ 8 days = 12 workers.

  7. A store buys shirts for $22.50 each and sells them at a 40% markup. During a clearance sale, the store discounts all shirts by 25%. What is the final selling price during the sale?

    Answer: $23.63

    Marked-up price = $22.50 × 1.40 = $31.50. Sale price = $31.50 × (1 − 0.25) = $31.50 × 0.75 = $23.625 ≈ $23.63.
