Question 1190216
<font color=black size=3>
x = number of days


Antonio has sold 6 tubs already. 
He sells 1 per day, for x number of days, so he sells an additional 1*x = x tubs on top of the 6 already done.
x+6 = total amount Antonio has sold


Taylor sells 3x tubs total because they sell 3 per day, and they started off 0 sold already.


When will they sell the same amount? That happens when x = 3 as shown by the steps below


Antonio's amount = Taylor's amount
x+6 = 3x
6 = 3x-x
6 = 2x
2x = 6
x = 6/2
x = 3


Antonio's amount = x+6 = 3+6 = <font color=red>9</font>
Taylor's amount = 3x = 3*3 = <font color=red>9</font>
By day 3, each person has sold <font color=red>9</font> tubs


If you wanted, you can make a table like this<table border = "1" cellpadding = "5"><tr><td>Day</td><td>Antonio</td><td>Taylor</td></tr><tr><td>0</td><td>6</td><td>0</td></tr><tr><td>1</td><td>7</td><td>3</td></tr><tr><td>2</td><td>8</td><td>6</td></tr><tr><td>3</td><td><font color=red>9</font></td><td><font color=red>9</font></td></tr></table>which helps confirm we have the correct answer.
