Final answer:
Aslam's percentage increase in pay from $10.00 to $12.00 per hour, working at a supermarket, is calculated to be 20%, making the correct answer C. 20%.
Step-by-step explanation:
Aslam works in a supermarket for $10.00 per hour and has received an increase in pay to $12.00 per hour. To calculate Aslam's percentage increase in pay, we use the formula for percentage change:
Percentage change = (Change in quantity / Original quantity) × 100%
In Aslam's case, the change in pay is $12.00 - $10.00 = $2.00. His original pay was $10.00 per hour. Plugging these values into the formula gives us:
Percentage change = ($2.00 / $10.00) × 100% = 0.20 × 100% = 20%
Therefore, the answer is C. 20%.
