Question

Last month you spent ​$40 on clothing. This month you spent ​120% of what you spent last month. Set up a proportion to model this situation. How much did you spend this​ month?

Answer 1

$48

Explanation:

Given that:

Money spent on clothing last month = $40

Money spent this month is 120% of the spending of the last month.

To find:

A proportion to model this situation.

And the spending done this month?

Solution:

Let us have a look at 120% first.

`120\%= (120)/(100) = (6)/(5)`

`(6)/(5)` of
`x` can be found by comparing
`x` with 5, then we have to find the equivalent of 6.

Here,
`x` is 40.

5 parts are equivalent to 40

1 part is equivalent to
`(40)/(5) = 8`

6 parts are equivalent to
`8* 6 = 48`

OR

simply:

`40 * (120)/(100) = 48`
