Question

Nghiep gave his mother half of his weekly earnings and then spent half of what was left on a new shirt. He then had $34. What were his weekly earnings (in dollars)?

Answer 1

Hence the weekly earnings of Nghiep= $136

Explanation:

Let the weekly income of Nghiep be $ x.

As it is given that:

• Nghiep gave his mother half of his weekly earnings i.e. the amount he gave to his mother= $ (x/2).

So now we will be left with= $(x/2).

• Next he then spent half of what was left on a new shirt.

so the amount he spent on his shirt= $ (x/4)

Now he will be left with = $ (x/4).

Now it is given that the amount he had after spending on his shirt and giving to his mother= $ 34

i.e.
`(x)/(4)=34\\\\x=34* 4\\\\x=136`

Hence, the weekly earnings of Nghiep= $136.
