Question

1. GASOLINE The table gives the cost of a gallon of gasoline at tro stations. How much more does gasoline cost at Gas For Less than at Cur-Rate? cut-rare : -2x+3.5 gass for less :x-1.2

Answer 1

The gasoline at Gas for less cost (3x-4.7) more

Here, we want to get a difference in cost

We want to get the difference between the cost at Gas for less and at cut-rate

We simply have to subtract the value of cut-rate from gas for less

We have this as;

$\begin{gathered} (x-1.2)-(-2x+3.5) \\ =\text{ x-1.2+2x-3.5} \\ =\text{ x+2x-1.2-3.5} \\ =\text{ 3x -4.7} \end{gathered}$
