Oisín earns €30 000 per year - Junior Cycle Mathematics - Question 6 - 2018

To calculate Oisín's net pay, we first need to determine the tax owed after considering the tax credits:

1. Calculate the total tax before credits:

   $$\text{Total Tax} = \text{Gross Tax} = 6{,}000$$

2. Subtract the tax credits:

   $$\text{Net Tax} = \text{Total Tax} - \text{Tax Credits} = 6{,}000 - 3{,}300 = 2{,}700$$

3. Finally, find the net pay by subtracting the net tax from the gross income:

   $$\text{Net Pay} = 30{,}000 - 2{,}700 = 27{,}300$$

Therefore, Oisín's net pay per year is €27,300.

To determine Aoife's new weekly pay after her raise, we can utilize the following calculation:

1. First, calculate the amount of the raise:

   $$\text{Raise} = \text{Current Pay} \times \text{Raise Rate} = 800 \times 0.05 = 40$$

2. Then, add the raise to her current pay:

   $$\text{New Pay} = \text{Current Pay} + \text{Raise} = 800 + 40 = 840$$

Thus, Aoife’s weekly pay after the pay rise is €840.
