*Given
Money of Phoebe - 3 times as much as Andy
Money of Andy - 2 times as much as Polly
Total money of Phoebe, - <span>£270
</span> Andy and Polly
*Solution
Let
B - Phoebe's money
A - Andy's money
L - Polly's money
1. The money of the Phoebe, Andy, and Polly, when added together would total <span>£270. Thus,
</span>
B + A + L = <span>£270 (EQUATION 1)
2. Phoebe has three times as much money as Andy and this is expressed as
B = 3A
3. Andy has twice as much money as Polly and this is expressed as
A = 2L</span> (EQUATION 2)
<span>
4. This means that Phoebe has ____ as much money as Polly,
B = 3A
B = 3 x (2L)
B = 6L </span>(EQUATION 3)<span>
This step allows us to eliminate the variables B and A in EQUATION 1 by expressing the equation in terms of Polly's money only.
5. Substituting B with 6L, and A with 2L, EQUATION 1 becomes,
6L + 2L + L = </span><span>£270
</span> 9L = <span>£270
</span> L = <span>£30
So, Polly has </span><span>£30.
6. Substituting L into EQUATIONS 2 and 3 would give us the values for Andy's money and Phoebe's money, respectively.
</span>
A = 2L
A = 2(£30)
A = £60
Andy has £60
B = 6L
B = 6(£30)
B = £180
Phoebe has £180
Therefore, Polly's money is £30, Andy's is £60, and Phoebe's is £180.
Answer:
The probability that a randomly selected consumer will recognize Amazon is 0.988.
Step-by-step explanation:
The data given in the question is
Total number of consumers = 795 + 10 = 805
Consumers who knew of Amazon = 795
Consumers who did not know of Amazon = 10
The formula for calculating probability of an event A is:
P(A) = No. of favourable outcomes/Total no. of possible outcomes
P(Recognize Amazon) = No. of Consumers who knew Amazon/Total no. of consumers
P(Recognize Amazon) = 795/805
= 0.98757
P(Recognize Amazon) ≅ 0.988
The probability that a randomly selected consumer will recognize Amazon is 0.988.
