(a) Represent this information on a pie chart.
(b) Find his savings at the end of the year if his annual salary was N60,000.00.
Verified Correct Answer: .
Step-by-Step Mathematical Solution
Angle of sector:
\(Food = \frac{30}{100} \times 360^\circ = 108^\circ\)
\(Rent = \frac{18}{100} \times 360^\circ = 64.8^\circ\)
\(\text{Car Maintenance} = \frac{25}{100} \times 360^\circ = 90^\circ\)
\(Savings = \frac{12}{100} \times 360^\circ = 43.2^\circ\)
\(Taxes = \frac{5}{100} \times 360^\circ = 18^\circ\)
\(Others = \frac{10}{100} \times 360^\circ = 36^\circ\)
(a)
(b) Annual Salary = N60,000.00
\(\therefore Savings = N(\frac{12}{100} \times 60,000) = N7,200\)
