Since the average income rose from $12200 to $16300, the rise is $4100(16300 - 12200)

This represents an increase of \(\frac{4100}{12200} * 100 = \frac{400000}{12000}\) = approximately \(33\frac{1}{3}\)% (Option C)

Solution



    • Initial average income \(= $12,200\)

    • Final average income \(= $16,300\)

    • Thus, percentage increase \(= (\frac{Final}{Initial} – 1) * 100\)

    o Percentage increase \(= (\frac{16300}{12200} – 1) * 100 = \frac{41}{122} * 100 = \frac{40}{120} *100 = 33 \frac{1}{3}\)%

Correct Answer: Option C

Percentage increase = \(\frac{(New - Old)}{Old}\) x 100 =\(\frac{(16300 - 12200)}{12200}\) x100
= \(\frac{4100}{12200}\) x100 = Approx. \(\frac{1}{3}\) x100 = 33 \(\frac{1}{3}\)%

We can use the percent change formula (New - Old)/Old x 100:

(16,300 - 12,200)/12,200 x 100 = 4100/12200 x 100 ≈ 4,000/12,000 x 100 = ⅓ x 100 = 33 1/3 %
