A worker earns hourly pay at rate r for h hours and receives a fixed weekly gas allowance of 50 dollars. Which expression represents gross weekly pay?

• A. hr + 50
• B. h(r + 50)
• C. hr - 50
• D. hr × 50

Answer: (A)

Combining hourly pay with a fixed weekly allowance requires adding the two parts. The pay earned from hours is rate times hours, which is hr. The gas allowance is a fixed 50 dollars each week, so you add that to the hourly earnings. The total gross weekly pay is hr + 50. This reflects adding a fixed amount to the earnings from work, rather than multiplying or subtracting it. Why the other forms don’t fit: multiplying by 50 would treat the allowance as something earned per hour, which isn’t the case. Including the 50 inside the parentheses would imply the allowance scales with hours. Subtracting 50 would reduce earnings, which isn’t correct for a fixed weekly allowance.
