Answer:
B.
Step-by-step explanation:
- Multiplying both numerator and denominator by (5 - 4i) <em>,</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>c</em><em>o</em><em>n</em><em>j</em><em>u</em><em>g</em><em>a</em><em>t</em><em>e</em><em> </em><em>o</em><em>f</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>d</em><em>e</em><em>n</em><em>o</em><em>m</em><em>i</em><em>n</em><em>a</em><em>t</em><em>o</em><em>r</em><em>,</em><em> </em><em>i</em><em>.</em><em> </em><em>e</em><em>,</em><em> </em><em>(</em><em>5</em><em> </em><em>+</em><em> </em><em>4</em><em>i</em><em>)</em><em>.</em>
- Multiplying (4+4i) and (5-4i) using distributive property
- Using the identity <em>(a+b)(a-b)= a² - b²</em> where 5 will act as a and 4i will act as b
(<em>combining like terms)</em>
distributing the denominator
That is, option B.
After the tax and the tip are counted, we conclude that each friend must pay $30.
<h3>How much should each person pay?</h3>
We know that the meal cost is $72.50.
Now, there is a 6.75% sales tax and a 15% tip on the waiter (we assume that the tip is based on the total meal cost, after the tax is applied).
Then the total meal cost is:
C = $72.50*( 1 + 6.75%/100%) = $72.50*(1 + 0.0675) = $77.39
Now we also need to add the tip, which is a 15% of that, so the total cost with the tip included is:
C' = $77.39*(1 + 15%/100%) = $88.998 = $90
(Where we rounded up).
Then, if there are 3 friends, each one must pay:
$90/3 = $30
Each friend must pay $30.
