Final answer:
Rhonda's sister's rate of pay at Macy's is $5.00 per hour, calculated by dividing her total paycheck by the hours worked. Additionally, if a job that pays $10 per hour offers a $2 raise, the percentage change in pay is 20%.
Step-by-step explanation:
Rhonda's sister's rate of pay per hour can be calculated by dividing her total paycheck by the total number of hours she worked. She received a paycheck of $125.00 for working 25 hours.
To find her hourly wage, we perform this calculation: $125.00 ÷ 25 hours = $5.00 per hour.
Therefore, her rate of pay per hour is $5.00.
Similarly, if we want to calculate the percentage change in pay for a job that pays $10 per hour and then receives a $2 per hour raise, we use the formula: percentage change = (raise ÷ original pay) × 100%. In this case, the percentage change would be ($2 ÷ $10) × 100% = 20%.
