The slope is y/x 20/4=5 meaning as it rises 5 feet it will horizontaly change by 1 foot
The quotient of a number and 12
Quotient means division.
The answer is C.) n/12
If you have any questions feel feee to ask.
Hope this helps.

Let
, so that differentiating both sides wrt
gives

If
and
, the above reduces to

This is the slope of the tangent line, which has equation

The answer would be $42.4. $50 minus $10 is $40. Multiply that by 106% because of tax, and you get $42.4.

Well, one divides by 7, actually, because the total number of tickets is 6+1 times the # of discount tickets. That is, 1,456/7. You don't need to actually perform this division.
