Answer:
RN = registered nurse
LPN = licensed practice nurse
RN earns $21.50 per hr
LPN earns $14 per hr
To calculate earnings for a 40 hour working week, multiply the rate per hour by 40:
RN earns: 21.50 × 40 = $860 per week
LPN earns: 14 × 40 = $560 per week
Difference: 860 - 560 = $300
Therefore, an RN is paid $300 more than an LPN for a 40 hour working week.
Number of weeks in a (non leap) year = number of days in a year ÷ 7
= 365 ÷ 7
= 52.14285714...
Rounding to the nearest whole number ⇒ 52 weeks in a year
To calculate the yearly salary, multiply the rate per week by 52:
RN earns: 860 × 52 = $44720 per year
LPN earns: 560 × 52 = $29120 per year
Difference: 44720 - 29120 = $15600
OR we can simply multiply the difference between the amount paid for a 40 hour week by 52:
⇒ 300 × 52 = $15600
Therefore, an RN is paid $15600 per year than an LPN.
