b Work out what percentage of his income he pays in tax.
c If the income tax rate is increased to 21%, how much more tax will Sam pay?

See all three answers below

Step-by-step explanation:

Given data

Amount Earned= $54275

Income Tax= 18%

a Work out how much income tax he pays.

Amount of income tax

=18/100*54275

=0.18*54275

=$9769.5

b Work out what percentage of his income he pays in tax.

=9769.5/54275*100

=0.18*100

=18%

c. If the income tax rate is increased to 21%, how much more tax will Sam pay?

=21/100*54275

=0.21*54275

=$11397.75

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
