Question 1 Report

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

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

85 + x = 100.
x = 100 - 85

x = 15

items	%	degree
food & drinks	35	$\frac{35}{100} * 360$ = 126º
fuel	7.5	$\frac{7.5}{100} * 360$ = 27º
rent	10	$\frac{10}{100} * 360$ = 36º
building project	15	$\frac{15}{100} * 360$ = 54º
education	17.5	$\frac{17.5}{100} * 360$ = 63º
savings	15	$\frac{15}{100} * 360$ = 54º

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

Monthly tax = $\frac{3456}{12}$ = $288.00

(ii) Monthly net salary = $\frac{1}{12} (288 - 3456)$ = $2,112.00

Amount saved each month = $\frac{15}{100} * 2112$ = $316.80
