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} (2x)/(2)=(6)/(2) \\ x=3 \end{gathered}`

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