(b) How much does he earn in one hour?
(e) For working 3 nights per week, he earns an extra allowance of $30.00 per

week?​

Answer 1

Step-by-step explanation:

(a)23:15 in 12 hours clock is 11:15 pm

he works 7 hours each night

after 7 hours the time will be 6:15 am

so he will be finishing his work at 6:15 am

(b) He earns $67.50 each night

Per hour he earns

67.50÷7

=$9.64

So he will be earning $9.64 per hour

(c) For working 3 nights per week, he earns an extra allowance of $30.00 per

week.

per night his extra allowance is 30÷3=10

if he works 5 nights per week than his extra allowance will be 5×10=50.

He earns $67.50 each night

then his total allowance for working 5 nights in a week is

5(67.50+10)=387.5

his total allowance for working 5 nights in a week is $387.5
