Answer:
50 sofas
Explanation:
We know
A sofa made costs $600
1 sofa sell = $750
750 - 600 = $150
So, the profit is $150 for each sofa
setup cost = $4500
Let x be the number of sofas, and we have the equation
12000 = 150x + 4500
Now let's solve
12000 = 150x + 4500
7500 = 150x
x = 50 sofas
So, they need to sell 50 sofas to turn a profit of $12000
