Answer :
Answer:
At weekday job, he worked for 25 hours,
At weekend job, he worked for 15 hours.
Step-by-step explanation:
It is given that the person works for 40 hours a week.
Let the hours spent at weekdays job be "x" hours.
Then hours spent at weekend job is (40 - x) hours.
Money earned at weekday job is [tex](20)(x)[/tex].
Money earned at weekend job is [tex](18)(40-x)[/tex].
Total money earned is $770. It is also equal to the above total earnings.
[tex](20)(x) + (18)(40-x) = 770[/tex]
[tex](2)(x) = 50[/tex]
[tex](x) = 25[/tex],
thus, hours spent are 25 and (40 - 25) 15 hours.
