The table below shows the relation between number of tables sold and the cost of the table. Find the unit rate.

• A. 100 dollars
• B. 200 dollars
• C. 300 dollars
• D. 400 dollars

Answer 1

The correct option is B 200 dollars

$\text{Unit rate =}\frac{Rise}{Run}$

$=\frac{800-400}{4-2}$

$=\frac{400}{2}$

$=200$

Hence, cost of 1 table is 200 dollars.
