Answer:
$48
Step-by-step 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.
of
can be found by comparing
with 5, then we have to find the equivalent of 6.
Here, is 40.
5 parts are equivalent to 40
1 part is equivalent to
6 parts are equivalent to
OR
simply:
which makes no sense, our variable went poof, but that is a flag that this system has no solution, let's quickly solve both for "y" to put them in slope-intercept form,
so, notice, the slopes(m) are exactly the same for both, whilst the y-intercept differs, meaning both lines are parallel and therefore never touch each other, thus, no solution.
the untrue equation of -20 = 5, is another way to say, "no solution".
