Answer:
3 movies
Step-by-step explanation:
55$-40.99$= 14.01$ left to spend on movies
$14.01/$3.95=3.54
Which means you can buy 3 movies.
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.
Take 770- 10 and that will be your answer
