What percentage of the sales of coupes were negotiated by Lydia?
To find the percentage of the sales of coupes negotiated by Lydia, we need to divide the number of coupes negotiated by Lydia by the total number of coupe sales, and then multiply by 100.
The number of coupe sales negotiated by Lydia is 12.
The total number of coupe sales is 31.
(12 / 31) * 100 = 38.71%
Therefore, 38.71% of the sales of coupes were negotiated by Lydia.
