<em>Heyy there, it's Avery. And I'm here to help! :)
</em>----------------------------------------------------------------------------------------------------------[<The Explanation>]:
Let x= number of watches sold
<em>Ethan= x(14) + (20)(1.50)</em>
<em>Roy = x(13.50) + (20)(1.80)</em>
Since they collected the same amount of money:
<em>14x + (20)(1.50) = 13.50x + (20)(1.80)</em>
Combine like terms:
<em>14x - 13.50x = (20)(1.80) - (20)(1.50)</em>
<em>0.50x = 36 - 30</em>
<em>0.50x = 6</em>
<em>x = 6/0.50</em>
<em>x= 12</em>
Ethan sold 12 watches. And also Roy.
Andddd...We're done! :D
