Respuesta :

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.
