At tire depot a pair of new tires sells for $216. the managers special advertises the same tires selling at a rate of $380 for 4 tires. how much do you save per tire if you purchase the managers special? ( how do you do this and what is the answer)

To find how much you save, you need to find out how much you pay for each tire. Your 2 equations are

2x=216    (x being the price of the tire, which you do not know)

x=108

4x=380

x=95

As you can see, the price of the tire from the manager's special is cheaper, but to find out by how much you subtract.

108-95=13

So you save $13 per tire.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
