Braxton loves downloading new music he originally had 41 songs but plans to purchase 4 new songs each week. he wants to know how many new songs he will have after 110 weeks. which equation should he use? a)a110=41+4(110-1) b)a110=41+4(110+10 c)a110=110+4(41-1) da110=110+4(41+1)

Step-by-step explanation:

He already has songs = 41

Since we are given that he purchase four songs every week .

So, in first week he purchase songs = 4

Initially he already has 41 songs

So, total songs after 1 week =

After 2 weeks he will have songs =

This forms an arithmetic sequence  : 41,45,49......

Formula of nth term in A.P. :

a = first term = 41

d = common difference = 45-41=49-45=4

Since we are required to find the new songs after110 weeks

So, n =110

Substituting values :

Thus Option A is correct.
