Question 1: A warehouse worker earns $14.75 per hour and works 42.5 hours in a week. Hours beyond 40 are paid at 1.5 times the regular rate. What is the worker's total weekly pay?
- $626.88
- $645.31 (Correct answer)
- $662.75
- $608.44
Correct answer: $645.31
Regular pay: 40 × $14.75 = $590.00. Overtime rate: $14.75 × 1.5 = $22.125. Overtime hours: 2.5. Overtime pay: 2.5 × $22.125 = $55.31. Total: $590.00 + $55.31 = $645.31.
Question 2: A delivery truck gets 8.4 miles per gallon and must travel 378 miles. If diesel costs $3.85 per gallon, what is the total fuel cost for the trip?
- $145.00
- $158.50
- $173.25 (Correct answer)
- $189.75
Correct answer: $173.25
Gallons needed: 378 ÷ 8.4 = 45 gallons. Total cost: 45 × $3.85 = $173.25.
Question 3: A concrete mix requires 2 parts cement, 3 parts sand, and 4 parts gravel by weight. If a job requires 135 kilograms of gravel, how many kilograms of cement are needed?
- 45.0
- 60.0
- 67.5 (Correct answer)
- 75.0
Correct answer: 67.5
The ratio of cement to gravel is 2:4. Set up the proportion: 2/4 = x/135. Solving gives x = 135 × (2/4) = 67.5 kilograms of cement.
Question 4: A store marks up a wholesale item by 40% and then applies a 15% sale discount on the marked-up price. If the wholesale cost is $120, what is the final sale price?
- $130.80
- $138.60
- $142.80 (Correct answer)
- $151.20
Correct answer: $142.80
Marked-up price: $120 × 1.40 = $168.00. After 15% discount: $168.00 × 0.85 = $142.80. Note that the discount is applied to the marked-up price, not the original cost.
Question 5: A restaurant bill totals $67.50 before tax. A sales tax of 8.5% is added, and the customer leaves an 18% tip calculated on the pre-tax amount. What is the total amount paid?
- $83.25
- $85.39 (Correct answer)
- $87.48
- $91.12
Correct answer: $85.39
Tax: $67.50 × 0.085 = $5.74. Tip: $67.50 × 0.18 = $12.15. Total: $67.50 + $5.74 + $12.15 = $85.39.
Question 6: A bakery arranges muffins on 5 shelves. The bottom shelf holds 15 muffins, and each shelf above holds 3 fewer muffins than the one below it. How many muffins are displayed in total?
- 40
- 42
- 45 (Correct answer)
- 48
Correct answer: 45
The shelves hold 15, 12, 9, 6, and 3 muffins from bottom to top. Total: 15 + 12 + 9 + 6 + 3 = 45 muffins.
