Using the unit data by product line, compile a breakdown of sales by product line. Alpha = 218, beta 203 and gamma 107

What percentage of the total sales is for each product line?
Also, currently the sales total equals 528,000 units.
If the sales total was changed to 100,000 total units, how many units will Alpha, Beta, and Gamma have?

Is the current sales total 528,000 or 528? Are you using European notation (a comma) for the decimal point?

In any event, convert the fraction to a percentage.

There is no reason to believe that percentages will remain the same if the number of total units sold is drastically reduced.
