Question

The graph given below shows the price of apples sold in a fruit shop. Find the unit rate.

• A. 0.2 dollars
• B. 0.4 dollars
• C. 0.6 dollars
• D. 1 dollar

Answer 1

The correct option is A 0.2 dollars

Consider two points (3,0.6) and (6,1.2) on the graph.

$\text{Slope =}\frac{1.2-0.6}{6-3}=\frac{0.6}{3}=0.2$

Hence, rate of 1 apple = 0.2 dollar
