Question

During his 2nd week on the job, Jason earned $110. This represented a 25 percent increase over his earnings of the previous week. How much did he earn during his first week of work?

Answer 1

Let money earned in previous week =x

Money earned in second week =$110

money earned in 2nd week represents 25 percent increase over his earnings of the previous week.

110= x+25% of x

110= x+0.25 (x)

110=1.25x

x=110/1.25

x=88

So money earned during previous week is $88

Answer 2

He earned $ 88 during his first week of work.

Explanation:

Let x be the earning of Jason in his first week of work,

Also, his earning is increased by 25 % in the second week,

So, his earning in the second week of work = x + 25 % of x

`=x+(25x)/(100)`

`=x+0.25x`

`=1.25x`

According to the question,

In his second week he earned $110,

`\implies 1.25x=110`

`\implies x = (110)/(1.25)=88`

Hence, he earned $ 88 during his first week of work.
