Answer:
Price per ounce is $0.062
Step-by-step explanation:
Here, we want to find the unit price in which this vase is price per ounce
Firstly, we need the total ounce value
1 pound = 16 ounce
so two pounds will be 2 * 16 = 32 ounces
So the total ounce value is 32 ounces + 8 ounce = 40 ounces
So 40 ounces = $2.48
price per ounce will be $2.48/40 = $0.062 per ounce
Obviously the smallest odd number we are looking for will have the SMALLEST four prime factors.
The smallest four prime numbers are 2,3,5,7. The lowest multiple of this is 2*3*5*7 = 210 But this is an even number!
So let's remove 2, and use the next prime number: 3,5,7,11. The lowest multiple of these is 3*5*7*11 = 1155.
