The table shows the monthly expenditure (in percentages) of Mr. Okafor's salary.

(a) Calculate the percentage of Mr. Okafor's salary that was. put into salary.

(b) Illustrate the information on a pie chart.

(c) If Mr. Okafor's annual gross salary is $28,800.00 and he pays tax of 12%.

Calculate: (i) his monthly tax; (ii) amount saved each month.

Answer Details

(a) 35 + 7.5 + 10 + 15 + 17.5 + x = 100

85 + x = 100.
x = 100 - 85

x = 15

(c) income tax = 12100∗28,800 $\frac{12}{100}\ast 28,800$ = $3,456.00

Monthly tax = 345612 $\frac{\mathrm{<br>}}{}$ = $288.00

(ii) Monthly net salary = 112(288−3456) $\frac{\mathrm{<br>}}{}$ = $2,112.00

Amount saved each month = 15100∗2112 $\frac{\mathrm{<br>}}{}$ = $316.80
