B. Prove: For all integers n > 1, if n is not prime, then there exists a prime number p such that p ≤√n and n is divisible by p.(Hints: Use the result of part (a) and Theorems 4.3.1, 4.3.3, and 4.3.4.)

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.
