Viola makes gift baskets for Valentine’s Day. She has 13 baskets left over from last year, and she plans to make 12 more each day. If there are 15 work days until the day she begins to sell the baskets, how many baskets will she have to sell?

$$a_n=a_1+(n-1)d$$
$$a_n = 13 + (15 - 1)12$$
181?

Wouldn't it be total=12d+13?
So 12(15)+13=193

I don't know :/

Why do you have the -1 in your equation?

anonymous · Answer

I was following this http://www.regentsprep.org/Regents/math/algtrig/ATP3/Recursive.htm

Ah, I looked at it like this. She already has 13 baskets made and she plans on making 12 baskets each day for 15 days. So the equation to find how many she has on day 15 would be 12(15)+13. I don't believe this is a recursion problem.

anonymous · Answer

If you wanted to make it an equation you could make it 12a + 13, where a is the number of days she's been making baskets
