Question

The following graph shows the quantity of sugar needed to prepare lemonade. Find the quantity of sugar needed to prepare 1 lemonade.

• A. 1.5 ounces
• B. 2 ounces
• C. 2.5 ounces
• D. 3 ounces

Answer 1

The correct option is A 1.5 ounces

The unit rate represents the slope of the line.

To find the unit rate, take two coordinates (2,3),(4,6) on the line.

$\text{Slope (m) =}\frac{rise}{run}$

$=\frac{6-3}{4-2}$

$=\frac{3}{2}$

$=1.5$

Hence, sugar needed to prepare 1 lemonade is 1.5 ounces.
