Home Depot wants to buy a new line of fertilizers. Manufacturer A offers a 22/19 chain discount. Manufacturer B offers a 25/14 c

Temka [501]

Answer: A is 36.82%. B is 35.5%

Step-by-step explanation: For manufacturer A 22/19 chian discount simply means 22% discount followed by 19% discount.

Therefore we have 100-22= 78 and 100-19=81.

The final price would be 0.78*0.81=0.6318

Therefore discount would be

1 - 0.6318=0.3682

Hence, percentage discount would be 0.3682*100%=36.82%.

For manufacturer B 25/14 chian discount means 25% discount followed by 14% discount. So we have 100-25=75% and 100-14= 86%

Final price would be 0.86*.75=0.645.

Discount= 1 - 0.645= 0.355.

Percentage discount would be 0.355*100%=35.5%.

<u>Complete Question</u>

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom. The results are: 59 for Bride, 50 for Groom, 30 for both. Find the probability that a randomly selected person from this sample was a friend of the bride OR of the groom.

Answer:

0.9875

Step-by-step explanation:

Total Number of Guests, n(S)=80

Let the Event (a friend of the bride) =B

Let the Event (a friend of the groom) =G

n(B) =59

n(G)=50

$n(B \cap G)=30$

Therefore:

$n(B \cup G)=n(B)+n(G)-n(B \cap G)\\n(B \cup G)=59+50-30\\n(B \cup G)=79$

Number of Guests who was a friend of the bride OR of the groom = 79

Therefore:

The probability that a randomly selected person from this sample was a friend of the bride OR of the groom.

$P(B \cup G) =\dfrac{n(B \cup G) }{n(S)} \\\\=\dfrac{79 }{80}\\\\=0.9875$
