Final answer:
The statement that a composite unit of Elli Inc's sales consists of .25x and .75y is false. The actual ratio is 1x to 3y, or .33x to .67y, based on the sales figures provided.
Step-by-step explanation:
If Elli Inc sells 20,000 units of product x and 60,000 units of product y, we are looking at the composition of a theoretical composite unit that might be produced from these sales figures. By stating that a composite unit consists of .25x and .75y, the question appears to present a ratio of products x to y within each composite unit. However, the actual ratios based on the sales figures given are 20,000 units of x to 60,000 units of y, which simplifies to a ratio of 1:3, or .33x to .67y.
Therefore, the statement claiming that the composite unit consists of .25x and .75y is False. The correct composition based on the given data would more accurately be represented by .33x and .67y.
