Answer 1

Given:

Time has a total of $28 after spending half of his weekly earnings on a video game and earning $10 additional dollars for mowing the lawn.

To find:

Weekly earnings at his part time job.

Solution:

Let x be the weekly earning.

He spend half of his weekly earning, i.e.,
`(x)/(2)`

He earns $10 additional dollars for mowing the lawn.

According to the question,

`(x)/(2)+10=28`

`(x)/(2)=28-10`

`(x)/(2)=18`

Multiply both sides by 2.

`x=36`

Therefore, his weekly earnings is $36.
