Question

The sales report for bikes and scooters is given as:

Sale of bikes:
Sale of scooters: y = 8x

Number of bikes sold are the number of scooters sold.

• A. greater than
• B. less than
• C. equal to

Answer 1

The correct option is B less than

Given sale of bikes:
The points are (1,15), (2,20), (3,25)
Slope = $\frac{\text{Rise}}{\text{Run}}$

= $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{20-15}{2-1}$

Slope ($m_1$) = 5

Similarly,
Sale of scooters: y = 8x
When $x$ = 1, $y$ = 8
When $x$ = 2, $y$ = 16
When $x$ = 3, $y$ = 24

Plotting the points (1,8) , (2,16) , (3,24), and (1,15), (2,20), (3,25) from the table on the graph.

Slope ($m_2$) = 8
Slope ($m_1$) = 5



Since the slope of sale of scooters is steeper than sale of bikes, the number of bikes sold is less than the number of scooters sold.
