Help me plz i need this done soon ty :

A. $47,403.20

Step-by-step explanation:

D

Step-by-step explanation:

For this, the question is about Simple Interest, so the formula is PRT

p- principal (the amount of money you started with)

r- (rate, also the percentage)

t- time (the amount of time it says, in years or so)

So, they had $45,580

Multiply that by 4%, and 4% is 0.04 so multiply 0.04 x 45,580 = 1,823.20. So, the answer is D

Hope this helps!!

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
