Question

Jan buys x pounds of apples for $6. The apples cost $2 per pound. The cost can be modeledby the equation 2x 6. Plot a point on the number line to represent the value of x.

Answer 1

The cost of the apples can be modelled using the equation;

$2x=6$

The value of x can be calculated by dividing both sides by 2;

$\begin{gathered} \frac{2x}{2}=\frac{6}{2} \\ x=3 \end{gathered}$

So, Plotting the point x=3 on the number line we have;
