Suppose that we have the following sequence :
a_1=1
a_n=1/2 a_(n-1) , for n> 1
we define a new sequence as such :
b_1=a_1
b_n=b_(n-1)+a_n
find the 50th term of the sequence b_n.
find the 1th term of the sequence b_n.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
