I cant really see the question/photo.

Step-by-step explanation:

Can you maybe post another question with a bigger photo?

Step-by-step explanation:

Remark

His pay gets income tax deducted at a rate of 18% = 18/100

That means you multiply is weekly wage by 18/100 to get what the government takes off.

Solution

18/100 * 495 = 80.10

The government takes $80.10

His take home pay is 495 - 80.10 = $405.90

Note:

There is a short way of doing his take home pay if that is all you are interested in. His take home pay is 82% of his gross pay which is 82/100 * 495.

82/100 * 495 = 405.90

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
