To calculate the CPI, we need to first determine the base year value and the current year value for each good.

For Good A: 
Base Year (2000) Price = $10 
Current Year (2007) Price = $20 
Price Relative = (Current Year Price / Base Year Price) x 100 = (20/10) x 100 = 200

For Good B: 
Base Year (2000) Price = $5 
Current Year (2007) Price = $15 
Price Relative = (Current Year Price / Base Year Price) x 100 = (15/5) x 100 = 300

For Good C: 
Base Year (2000) Price = $2 
Current Year (2007) Price = $3 
Price Relative = (Current Year Price / Base Year Price) x 100 = (3/2) x 100 = 150

To calculate the overall CPI, we take the average of the price relatives for each good: 
CPI = (200 + 300 + 150)/3 = 216.67

Rounding to the nearest whole number, the approximate 2007 CPI using a 2000 base year would be 222. Therefore, the correct answer is C (222).
