Answer:
[tex][/tex] Let the dollar amount of shoes she sold be x.
Lane receives 16.5% commission for each pair of shoes sold, so the commission earned for selling x dollars worth of shoes is 0.165x.
Given that Lane earned $320 in commission last week, we can write the equation:
0.165x = 320
Solving for x:
x = [tex] \frac{320}{0.165}[/tex]
x = 1939.39 (approximately)
Therefore, the dollar amount of shoes Lane sold was approximately $1939.39.
