Calculate the new balance using the previous balance method.

previous balance = $34.80

finance charge = $0.75

new purchases = $83.21

payments/credits = $5.50

new balance = $

a.) 111.76

b.) 113.26

c.) 124.26

d.) -55.46

B.) 113.26

Step-by-step explanation:

Using the previous balance and the additional finance charge on the balance carried over, you can add the new purchase and subtract the credits to arrive at your new balance:

Previous balance = $34.80

Finance charge = $0.75

New purchases = $83.21

Total debt:  $118.76

Payment: - $5.50

New Balance: $113.26

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
