1) Change the word problem into an equation:
.5x+x=213.75 where x equal the amount of money Dave earns.
2) Combine the like terms: .5x+x=1.5x
3) Now solve: 1.5x=213.75 and use multiplicative inverse to get your answer of 142.5
4) Now wait, this is the amount Dave earns not the amount Monsiha earns, however we know that Monsiha earns half that, therefore:
142.5÷2=75.25
The answer would be 'Monsiha raised $75.25 in total'.

This is just from what I know I have no clue if it’s right
Let's say
is the measure of the first angle and
is measure of the supplement of
. We know that supplementary angles add up to 180°, so
. We also know that
. Therefore,
. It follows that
, therefore, the first angle is 174° and the second angle is 6°.
