C: $51.36

Step-by-step explanation:

Okay, so the first step you need to do is find 7% of $48.

To do that, all you have to do is multiply 0.07 and 48.  You should get $3.36.

The second and final step is to add 3.36 and 48.  You should get $51.36.

Therefore, the answer is C

Hope this helps!

$51.36

Step-by-step explanation:  You're finding tax on the material you're buying. The way you do that is 48 x 7% (7% gets converted to .07%) so you do 48 x .07%. You get 3.36. Then you add that to 48, for 51.36.

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.
