Answer:
If she sells 17 units, she earns $595
To earn $600, Mei must sell 18 units. Her revenue will be $630.
Explanation:
If Mei sells 17 ceramic vases, each one for $35, she will earn $35*17= $595. The formula I used above is:
Revenue ($)= Price ($)*Units sold
If she needs to earn $600, we need to transform the equation:
Units sold =Revenue($)/Price ($)
Units sold= $600/$35
Units sold= 17,14
Since Mei can not sell 17,14 units, then she must sell 18 units . Her revenue if she sells 18 units will be $630.
