Help me on this I really need it
CaHeK987 [17]

Answer:


Step-by-step explanation:

Given that sale of grills increase 6% per year

CUrrent sale of grills this year = 3300

So in the first year sales would increase by 3300(6%)

Total sales in the I year =3300+3300(6%)

This will be again increasing by 6% in II year and so on.

Hence we have

every year 3300 increases by 6% compoundly

So

No of sales in t year

=3300(1+0.06)^t\\=3300(1.06^t)

In 6th year sale

s(6) =3300(1.06)^6\\=4681.11
