Write a unit rate for the situation. $18 for 6 pounds

the unit rate would be 3 dollars per pound

Step-by-step explanation:

you need to divide 18 by 6 to get your answer

Okay. So, scientific notation is when a number greater than one but less than 10 is multiplied by a power of 10. The number that is being multiplied has to be a decimal. In word form, this number is one billion, three hundred twenty-two million. The decimal would be 1.322. D is eliminated, because it does not have that correct. A is wrong, because you don't multiply by 109 to get the answer. 10^8 is 100,000,000 and 10^9 is 1,000,000,000. 1.322 * 10^8 would give us 132,200,000. That's not the number we're looking for. 1.322 * 10^9 would give us 1,322,000,000. That is the number we're looking for. The answer is B.
