lina2011 [118]

Answer:

$33

Step-by-step explanation:

The travel allowance that Helen Ming receives is $220

The income tax rate is $15\%$

The amount she has to pay is calculated by multiplying the tax rate by the travel allowance.

$=\frac{15}{100}\times220$

We simplify to obtain

$=\frac{15}{10}\times22=33$

Therefore Helen Ming has to pay $33 form her benefit.

Step-by-step explanation:

Given

See attachment for complete question

Required

The missing step

The missing step is at step 2.

At step 1, we have:

$\frac{1}{2} - 2x +1 = -\frac{13}{2}$

At step 2, we have:

$\frac{3}{2} - 2x= -\frac{13}{2}$

What she did at step 2, is that:

She collected like terms; 1 and $\frac{1}{2}$

Then she simplified the like terms: $1 + \frac{1}{2} =\frac{3}{2}$

<em>Hence (a) is correct</em>
