problem 2 (show your work to get credit)
the following information shows the computer types in a survey.
a. use the tables information to construct a pie graph (you need first to find the percents and degrees - show your work i.e. write the formula for the degrees and percents and find them)
b. use the table to construct a pie graph.

	number	degrees	percents
red	48
black	117

Explanation:

Step1: Calculate total number

$97 + 48+117=262$

Step2: Calculate percent for Silver

Percent of Silver $=\frac{97}{262}\times100\%\approx37.02\%$
Degree of Silver $=\frac{97}{262}\times360^{\circ}\approx133.28^{\circ}$

Step3: Calculate percent for Red

Percent of Red $=\frac{48}{262}\times100\%\approx18.32\%$
Degree of Red $=\frac{48}{262}\times360^{\circ}\approx65.95^{\circ}$

Step4: Calculate percent for Black

Percent of Black $=\frac{117}{262}\times100\%\approx44.66\%$
Degree of Black $=\frac{117}{262}\times360^{\circ}\approx160.77^{\circ}$

Answer:

	Number	Degrees	Percents
Red	48	$\approx65.95^{\circ}$	$\approx18.32\%$
Black	117	$\approx160.77^{\circ}$	$\approx44.66\%$
