Given:
Total tips = $ 77.40
Ratio of tips sharing = 2 : 3 : 4
To find:
How much more does Brian get over Paul
Solution:
Let 2x, 3x and 4x be the cost of tips got by Paul, Colin and Brian.
Total cost of tips =$ 77.40
2x + 3x + 4x = 77.40
9x = 77.40
Divide by 9 on both sides.
x = 8.6
Brian gets = 4(8.6) = $34.4
Paul gets = 2(8.6) = $17.2
Difference = 34.4 - 17.2
= 17.2
Therefore Brian gets $17.2 more than Paul.
For this case, the first thing we must do is observe that the graph has two asymptotes.
A horizontal asymptote or equivalently:
A vertical asymptote or equivalently:
Therefore, the domain and the range of the function is the same:
All reals excluding zero.
Answer:
The domain and range is the mime:
All reals excluding zero.
