Is this correct? If it isn’t what’s the correct answer?

Answer:
No, it is 6.60
Step-by-step explanation:
We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20
We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.
If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.
Answer:
d. $6.60
Step-by-step explanation:
3 cost 3.60, then 5.5 would cost ?
So we have to find what multiplied with 3 would equal 5.5, so:
5.5/3, we can't simplify this fraction so we'll just use it to multiply 3.60
3.60 × 5.5/3 = 19.8/3 = 6.6
