Let's break this problem down step by step:

A. Calculate her weekly wage.

To calculate her weekly wage, divide her annual salary by the number of weeks in a year (52 weeks):

$\text{Weekly wage} = \frac{72800}{52} = 1400$

So, her weekly wage is $1,400.

B. Calculate her holiday loading.

Holiday loading is 17.5% of four weeks' pay. First, calculate her four weeks' pay:

$4 \text{ weeks' pay} = 4 \times 1400 = 5600$

Now, calculate 17.5% of this amount:

$\text{Holiday loading} = 0.175 \times 5600 = 980$

So, her holiday loading is $980.

C. Employer increased her annual salary by 1%. What is the new annual salary?

To calculate the new salary after a 1% increase:

$\text{New salary} = 72800 + (0.01 \times 72800) = 72800 + 728 = 73528$

So, her new annual salary is $73,528.

D. Why is she worse off financially with the 1% increase?

With the 1% salary increase, her new annual salary is $73,528, but the increase ($728) is less than what she was receiving as holiday loading ($980).

To explain more clearly:

• Original compensation: $72,800 salary + $980 holiday loading = $73,780 total.
• After the increase: $73,528 (without holiday loading).

Thus, with the 1% salary increase and the removal of holiday loading, her total compensation has decreased from $73,780 to $73,528, meaning she is $252 worse off.

---

Summary of answers:

• A. Weekly wage = $1,400
• B. Holiday loading = $980
• C. New annual salary = $73,528
• D. She is worse off by $252 because the 1% increase does not compensate for the removal of the holiday loading.

Would you like more details on any part of this? Here are 5 related questions to expand on this:

1. What is the equivalent monthly salary for her original annual salary of $72,800?
2. How much would her holiday loading be if her weekly wage increased to $1,500?
3. What would her salary be if her employer offered a 2% raise instead of 1%?
4. If her new annual salary was $75,000, would she be better or worse off compared to having holiday loading?
5. What percentage increase in salary would exactly match the amount of holiday loading she received?

Tip: Always compare total compensation (salary + benefits) to understand the true financial impact of a raise or change in benefits.
