x+y=15
Hope this helps!
No. 49 is not a multiple of 14. The only number that can do the job is 3.5 .
There are many pairs that are solutions to this inequality. You can find them all by graphic this on a coordinate plane and then shading the region.
You can also plug any of the ordered pairs that they give you into the equation and see if they produce a true statement.
To figure this out, you need to divide 28/8 to get the cost per hinge from Marks hardware
To figure out Steves Supplies cost per hinge you need to divide 38/11
Mark's = 28 / 8 = $3.50
Steve's = 38/11 = 3.45
Steve has the best deal because it cost $3.45 per hinge. The answer is C
