Alice earns £450 in wages per month. She pays £200 in rent per month. Next month, • her wages will increase by 2% • her rent will increase by 5% She says “The increase in my wages will pay for the increase in my rent” Is she correct? You must show your working.

Step-by-step explanation:

Wages

£450

450 x 1.02 = 459

Rent

£200

200 x 1.05 = 210

wages increases by £9

rent increases by £10

No the increase in her wages will not fully pay for the increase in the rent

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
