I think it should be E Statement 2 says sale is $180, it is possible they sell 1 writing pad for $180 (or) 'n' number of pads for $180. Since we dont know many many they sell, dont think we can determine the value of remaining stock. (again depends on how many they sold) I agree. Statement 1 tells ...

So my logic was as follows: If she bought: 1 bundle of 4 she would need to buy a single apple. 2 bundles, 2...

"Length of integer" (prime number properties)

For any integer k > 1, the term “length of an integer� refers to the number of positive prime factors, not necessarily distinct, whose product is equal to k. For example, if k = 24, the length of k is equal to 4, since 24 = 2 × 2 × 2 × 3. If x and y are positive integers such that x > 1, y > ...

I worked backwards on this one. The question said 11 x product of the set = even. in other words, odd (11) x even = even. Thus, the product of the set must be even. The question tells us that the set consists of only prime numbers. We know that the only even and prime number is 2. So K must be 2. Gr...

So, the regular rate (in cents) would be: r * 3 * x at a 50% discount, it would be: 3rx/2 To convert cents to dollars, we need to divide by 100 (since 100 cents = 1 dollar), so our final answer is: 3rx/2*100 = 3rx/200 I set up the equation like so: (3)(100r)(x)/(200) Where: 3: people 100r: converts...
