This is what I’m doing.

The average cost of gas where you live is $3.50 per gallon, you are trying to decide whether to buy a hybrid or standard car. The hybrid gives you 45 miles per gallon, and the standard gives you 25 mpg, the hybrid car costs $8,960 more than the
the standard.

What’s is the minimum miles you would need to drive in order for your savings on fuel to surpass the additional cost of the hybrid vehicle?

i dont know the answer but the fancier you get the better it is

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
