Answer:
She earns that day $103.5
Explanation:
Lets explain how to solve the question
- She is paid $12.50 per hour between 8 am and 4 pm
- After 4 pm she is paid $14.25 per hour
- She works one particular day from 10 am to 6 pm
* Lets distribute her time of work into two part according to her
payment above
# 1st part from 10 am to 4 pm
∵ She is paid $12.50 per hour between 8 am to 4 pm
∵ She works from 10 am to 4 pm
- Calculate how many hours between 10 am and 4 pm
∵ am and pm not like terms in time, so change the time to 24-hours
∵ 4 pm in 24-hour time is 4 + 12 = 16
∴ She works form 10 to 16
∴ She works for 6 hours (16 - 10 = 6)
∴ She is paid = 12.50 × 6 = $75
# 2nd part after 4 pm to 6 pm
∵ She is paid $14.25 per hour after 4 pm
∵ She works from 4 pm to 6 pm
- Calculate how many hours between 4 pm and 6 pm
∵ Both times are pm
∴ She works for 2 hours (6 - 4 = 2)
∴ She is paid = 14.25 × 2 = $28.5
- Add the two answers of the 1st part and the 2nd part
∴ She earns = 75 + 28.5 = $103.5
* She earns that day $103.5
