Respuesta :
The ratio here would be 4 to 18, in which 4 represents the number of
black covers sold and 18 represents the total of covers sold.
The correct answer is:
4:18, which means that 4 out of every 18 covers sold are black.
Explanation:
To find the ratio of black cases to total, we must first find the total number of cases sold: 5+6+3+4 = 18.
This makes the ratio of black to total 4:18.
The explanation is that 4 cases out of every 18 will be black.
