<h3>What are Chieftains?</h3>
The Chieftains are a traditional Irish folk band formed in Dublin in 1962, by Paddy Moloney, Sean Potts and Michael Tubridy. Their sound, which is almost entirely instrumental and largely built around uilleann pipes, has become synonymous with traditional Irish music and they are regarded as having helped popularise Irish music around the world.
They have won six Grammys during their career and they were given a Lifetime Achievement Award at the prestigious BBC Radio 2 Folk Awards in 2002. Some music experts have credited The Chieftains with bringing traditional Irish music to a worldwide audience, so much so that the Irish government awarded them the honorary title of 'Ireland's Musical Ambassadors' in 1989.

Answer: a) An = An-1 + An-2
b) 55ways
Step-by-step explanation:
a) a nickel is 5 cents and a dime is 10cent so a multiple of 5 cents is the possible way to pay the tolls in both choices.
Let An represents the number of possible ways the driver can pay a toll of 5n cents, so that
An = 5n cents
Case 1: Using a nickel for payment which is 5 cents, the number of ways given as;
An-1 = 5( n-1)
Case 2: using a dime which is two 5 cents, the number of ways is given as;
An-2 = 5(n-2)
Summing up the number of ways, we have
An = An-1 + An-2
From the relation,
If n= 0, Ao= 1
n =1, A1= 1
b) 45 cents paid in multiples of 5cents will give us 9 ways(A9)
From the relation, we have that
Ao = 1
A1 = 1
An =An-1 + An-2
Ao = 1
A1 = 1
A2 = A1+Ao = 1+1= 2
A3 = A2 + A1 = 3
A4 = A3+A2=5
A5=A4+A3=8
A6=A5+A4=13
A7 =A6+A5 = 21
A8= A7+A6= 34
A9= A8+A7= 55
So there are 55ways to pay 45cents.
We have to check which of PEMDAS rules can be applied in this case. We have only ADDITION. In this case we can observe that addition is:
1. Associative
2. Commutative
3. has Additive property
Step-by-step explanation:
12x + 3(x - 4) + 2x
17x-12
