it’s the cost of the lunch including the tip, so it’s over 13.00 and 17% of $13.00 is $2.21
Answer:
42.40
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 49.88 × 15/100
Discount = 49.88 x 0.15
You save = $7.48
Final Price = Original Price - Discount
Final Price = 49.88 - 7.482
Final Price = $42.40
Answer:
FV= $17,321.20
Step-by-step explanation:
Giving the following information:
Annual deposit (A)= $3,000
Number of periods (n)= 5 years
Interest rate (i)= 7.2% = 0.072
<u>To calculate the future value (FV), we need to use the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {3,000*[(1.072^5) - 1]} / 0.072
FV= $17,321.20
It is 1.75 dollars per packet of pens you just had to divide
<span>h<span>(t)</span>=<span>t<span>34</span></span>−3<span>t<span>14</span></span></span>
Note that the domain of h is <span>[0,∞]</span>.
By differentiating,
<span>h'<span>(t)</span>=<span>34</span><span>t<span>−<span>14</span></span></span>−<span>34</span><span>t<span>−<span>34</span></span></span></span>
by factoring out <span>34</span>,
<span>=<span>34</span><span>(<span>1<span>t<span>14</span></span></span>−<span>1<span>t<span>34</span></span></span>)</span></span>
by finding the common denominator,
<span>=<span>34</span><span><span><span>t<span>12</span></span>−1</span><span>t<span>34</span></span></span>=0</span>
<span>⇒<span>t<span>12</span></span>=1⇒t=1</span>
Since <span>h'<span>(0)</span></span> is undefined, <span>t=0</span> is also a critical number.
Hence, the critical numbers are <span>t=0,1</span>.
I hope that this was helpful.
