<h3>So lets say y = The amount of money that's made and x = The number of hours worked. We need two equations. one for Tammy and one for Lia. Tammy's equation will be: y=7x+4 because she makes 7 dollars an hour plus 4 dollars for every item she sells. Lia's equation should be: y=10x+3 because she makes 10 dollars an hour plus 3 dollars for every item she sells. Now since we need to know when they will make the same amount of money, we put both the equations together to make 7x+4=10x+3. Now lets use the distributive property to solve that equation. </h3><h3>7x+4=10x+3</h3><h3> -4 -4</h3><h3> 7x=10x-1</h3><h3> -10x -10x</h3><h3>-3x=-1</h3><h3>x=0.3 repeated)</h3><h3>Now we plug x into Lia's equation and solve that.</h3><h3>y=10(
)+3</h3><h3>y=3.33+3</h3><h3>y=6.33</h3><h3>Now we write our answer as an ordered pair: (0.33, 6.33) </h3><h3>Buuuuuuuuuuuttt you can't have 0.333333333333 of an item so the final answer here would be NO SOLUTION.</h3>
