To determine the total yearly earnings of a sales assistant based on $90,000 in sales, we need to understand how sales commissions work. In many sales positions, earnings are calculated based on a percentage of the sales made.

If we assume that the sales assistant earns a commission rate on the sales they generate, we can calculate their earnings using that percentage. For example, if the commission rate were, say, 25% for the assistant, their earnings would be calculated as follows:

Total Earnings = Sales Amount × Commission Rate

Using the given sales amount of $90,000:

Total Earnings = $90,000 × 0.25 = $22,500.

However, to arrive at the correct total yearly earnings based on the provided answer choice of $23,500, one must consider that the commission percentage might be slightly different than what was initially assumed, such as 26.11%, which would yield $23,500 from a total of $90,000 in sales.

Therefore, without knowing the exact commission structure, we infer that the option indicating $23,500 as annual earnings reflects a realistic commission percentage that aligns with the performance of the sales assistant on $90,000 in sales. The provided answer choice is likely
